Hi everyone

Im having this error when o load any level on Android.

This happens even with levels which are almost completely empty.

Doesn’t seem to showing this error when i work and test on the PC, just when running on Android.

Would really appreciate the help.

Ok, this one i kinda solved myself. There was a problem with the Default actor pawn.

Tnx again

I am hitting similar bug. What exactly was the issue with default actor pawn?

I encounter a similar error on UE 4.27. I would be very grateful if you could tell me how to fix it!

I just found out that there is a volatile tick box in the advanced section in sequence tab, under the spanner icon, that needs to be turned on if you ever change any component details at runtime of the sequence. Hope this helps.
