Trying to create unmanaged system inside of normal system's OnCreate.
Simply calling state.World.CreateSystem<T>() where T is same type as normal system calling it.
#[BUG] Bug in SortSystemUpdateList(), nAfter <= 0

Turns out error is due to update constraint attributes on T system

This probably needs a better message. Spent way too much time than I should

by normal system you mean system base?
what were the update constraints?
but this is a "can't happen" message, so definitely we should fix it so it doesn't happen
i guess i could modify it to say "this should never happen, please file a bug"

by normal system you mean system base?
no, the one that gets created automatically

what were the update constraints?
UpdateIn InitializationSystemGroup
UpdateAfter SceneSystemGroup
basically, just creating a system via World.CreateSystem will cause this error
even if it has DisableAutoCreation
as long as it has update constraints

and no creation constraints?

i see
ok just to make sure i understand: you have a system MySystem which calls state.World.CreateSystem<MySystem>() inside its OWN OnCreate method, trying to create another copy of itself?
and you have created the first instance of MySystem manually, via CreateSystem called from somewhere else?

ok just to make sure i understand: you have a system MySystem which calls state....
nah, I create it manually from bootstrap in a while loop
I tried to create it from OnCreate the very first time and it didn't work either

i would point out that creating systems from oncreate is basically always a bad idea, because the order can't respect any createafter or createbefore constraints
