PIE / Launch blueprint discrepancies

hi, i have a project that i am making with blueprints(4.6-4.7.4) and have noticed some troubling discrepancies between when i play in the editor and when i launch the game. for instance, i have a camera blueprint where i am using a Set Actor Location and some logic to move it, and when i play in the editor sometimes my blueprint changes just don’t show up, and sometimes strange things happen when i have made no changes at all. launching the game seems to be consistent and the changes appear, but the difference is disturbing and i would like to know why this is happening. i have also noticed that having a blueprint open when i run PIE seems to change the outcome. i have had cases where i will run PIE, and my blueprint is totally effed, and then i will open the blueprint in another window, do nothing, and run PIE again, and it works normally. what i need to figure out is if this is just a systemic problem with PIE, or if there is some flaw to my blueprint logic. i dont know if it could be a framerate thing, i am just using a Set Actor Location and i am not factoring in the Tick Delta into the math in the blueprint.

another example - my character has a custom movement mode where he wall runs, i am also using Set Actor Location in this, and even though i haven’t changed it in awhile, seemingly at random the character will struggle to run up the wall, probably going about half as high as he should. again this only happens in PIE.

any clues as to why this is happening would be greatly appreciated:)

Thisis strange and it never happened to me. Do you mind sending screenshots of the problematic actions?

i added a console command “stat fps” to the level blueprint, everything has been saved multiple times, and as you can see below, when i have the blueprint open in a window, the fps shows up, and when i close the window, it does not.

after further investigation i think this is two separate issues. there is an issue with my logic and i need to factor in the tick, then there is the issue of blueprint changes not showing up in PIE, and the randomness of them showing up depending on if the blueprint is open or not, which i still dont understand.
