@RaskVann I don't think this is the actual bug causing the problem. Because the problem kept appearing even without making any actual changes to the code. Anyway, after a day of this nonsense I got annoyed and just re-factored all the buggy code. I moved the spawnManager system in its own module and removed the queue system. Now 1 entry -> 1 spawn. No queueing entries, but at least it works fine.
