Blueprint Function Comments Being Lost Shortly After Adding Them

I am seeing a random problem with comments bubbles on functions & macros. Sometimes when I edit them, like 3-4 in a row, they can sometimes take the comment and accept it for a few moments, and then it will suddenly vanish a few moments later.

I am not seeing the problem on established comments, its only happening so far right after I’ve changed a comment bubble. Sometimes not all comments will be lost either. If I add 5 comments to 5 different functions, sometimes comment #1 and #3 vanish at the same time, but 2,4,5 don’t get cleared out. Sometimes they all do.

Whenever it happens, it happens to them all at the same time. (Or at least seems to)

So far I’ve not seen it happen on any comment greater than say 2 minutes in age. Its only on newly established function comments. So far I can’t see any consistent action I’m taking that makes them go away, and it doesn’t seem to matter if I typed the comment manually or pasted the same comment to multiple functions. I can also add the comment back again, and it can vanish again moments later. The age of the function doesn’t matter, just age of comment (so it seems).

I have not encountered the issue yet on the giant comment bubbles that group functions together, and I believe its happened in the level blueprints, but predominantly I’m seeing in class blueprints since that’s where I spend most of my time.

PC.

I have not worked much with Blueprint in prior versions, and definitely didn’t add as much comments when I was. I don’t recall if I encountered it in 4.9, but I don’t have anything as complex in 4.9 either. I don’t know if its related to blueprint complexity, but I am noticing it progressively more each day I’m working on the same class blueprint… but that’s possibly because I’m adding more comments than I was initially.

Toggle button. And it doesn’t matter how long the comment bubble has been open.

The bubble stays open, its the contents that vanish. The comment text is gone when I right click as well.

*I just saved and quit UE4 after adding 4 new comments. Relaunched, and all 4 didn’t even save, but they were visible after save and when I quit.

Hello,

I have attempted to reproduce your issue with the comment bubbles disappearing, but I have not been able to do so. I have a few questions that may help in reproducing this issue:

  • Are you on PC or Mac?
  • Does this only occur in 4.10?
  • Are you typing the comment by Right-Clicking on the node and adding the comment there, or by using the Toggle Comment Bubble button that appears above the node?
  • Is it just the comment bubble disappearing, or is the text disappearing as well? (Right-click on the node that has a missing comment and see if the text still appears in the comment box at the bottom of the properties window)

Have you been able to reproduce this issue in a clean project with no additional content? Also, to confirm, does this happen in any blueprints other than the complex class blueprint you are often working in?

I can replicate the issue on a blank project with no starter content.

I can replicate the issue on two computers that are not clones of one another.

OS is the most current build of Windows 10 Enterprise.

Create a new pawn class blueprint, make a few custom events, then comment them, save, and close the blueprint. Reopen it, and maybe all/some/none comments saved. Change them, and maybe the changes take effect, maybe they don’t.

I can replicate the bug in 4.9.2.

I cannot replicate the bug so far in 4.8.3.

Scratch that, I’ve now replicated it in 4.8.3.

Thank you for providing the additional information. I have unfortunately not been able to reproduce this issue as of yet. Could you provide your dxdiag so that I can see if it is a potential hardware conflict? Thank you.

Hello,

I was able to reproduce the issue based on information given on another user’s post: https://answers.unrealengine.com/questions/343234/bug-node-descriptions-desappearing-on-bp-functions.html
Please refer to that post for any new information regarding this issue.

Have a great day,
