Is there any chance you are updating things from the wrong thread?

That was my first guess but I’m enqueing all the code done on other threads on the main simple application rendering thread

do you have this exception on start, or when?

if on start, could you show simpleInitApp?

it can be caused, because of your earlier actions that destroy engine logic(in init or update loop), or it is just a BUG.

from actual stack trace it’s hard to deduce anything. even looking into source. the only thing we can know, it’s AssertionError.

I have it on runtime, looks like a race condition or something i’ll look more


u were right, totally running another thread and they seemed to conflict


in such situations it’s hard to find the issue. it’s good you found. :slight_smile:
