Converted my project today for 4.12 and have got 2 crashes.

First one happened with 4.12.2 when pressing play in editor to start session on streaming map (with mutliple levels). play in smaller testmap worked normally:

Assertion failed: LandscapeInfo [File:D:\Build\++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\Landscape\Private\LandscapeSplines.cpp] [Line: 811]

Then got the new 4.12.3. When loading the parent map that have streaming levels connected, got this crash:

Assertion failed: Index>=0 && Index<NumBits [File:D:\Build\++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\Core\Public\Containers\BitArray.h] [Line: 534]

Getting the LandscapeInfo crash also on 4.12.3.

Hey SaOk,

  • Could you please cause the crash to occur again, provide your Machine ID from the Crash Reporter window, and ensure to hit Send & Close on the report?
  • As far as the second crash goes, can you please create a new thread in the Bug Reports section regarding it? I’d like to investigate these separately. Please provide me with the link to the new post when you enter it.

Thank you.

Hi, the LandscapeInfo crash havent reappeared after I did map check, corrected some splines and saved the levels. I let you know if getting more crashes also make separate reports.

My MachineId is F87B756443F95CE9986941A672FE5264. But I have heard my crash reporter sent reports havent reached you guys before. Do you have some block enabled for my id? :slight_smile: I could have been sending too many reports since the restart button sends the report. Restart without sending button could be handy. :wink:

Since the LandscapeInfo crash is no longer occurring on your end, I’m going to mark this topic as resolved. Please move the second crash into a new post, if you have not already, and we will investigate that as a separate issue.

Also, to answer your question, we are able to see your Crash Reports, at least this time. There can be circumstances that will cause them to not get sent through properly, but that doesn’t seem to be occurring with your reports.

Actually, there is a feature request in our system for a Restart Without Sending button on the Crash Reporter window, UE-29307. Thanks for your suggestion!

Have a great day

Got again the LandscapeInfo crash and sent it. Its more rare but seems like not gone yet. In earlier builds didnt have the issue.

After some further investigation, it appears that this is a known issue, UE-32034. This crash is related to using Landscape Splines with Meshes in Sublevels. It is currently under investigation by our developers, but there is no timeline for when a fix will be released.

Have a great day

Great to hear it known issue. :slight_smile: Will work in my another testlevel meanwhile. I made a separate ticket now of that another crash:
