Hello, Anfilt!
Thanks for making a good mod.
But I was trying to play with this mod and suddenly an error occurred.

Error while running event beltutils.:on_entity destroyed (ID 159) beltutils/utils/entity-tracker.lua:26: attempt to index field?' (a nil value) stack traceback: - beltutils__/utils/entity-tracker.lua:26: in function 'remove_entity -beltutils__/utils/entity-tracker.lua:91: in function 'entry's - beltutils _ /control.lua:63: in function 'call_all_events'
beltutils _/controllua: 125: in function beltutils / controllua: 123>

Thank you .

It happens right away with the jetpack mod.

Thanks for reporting this, will look at more closely when I get home from work, but I think I already have an idea what the issue is.

Just pushed a quick update please let me know if that fixed it.

Not heard anything back so just gonna lock this thread.
