Got a crash when using Bob's Characters mod, it happened when I placed an Engineer body.

Getting the same error, but I don't have Bobs. Using MSI & Krastorio (plus a few others):

Error while running event ammo-loader::on_tick (ID 0)
ammo-loader/lib/TrackedSlot.lua:279: attempt to index field 'player' (a nil value)
stack traceback:
ammo-loader/lib/TrackedSlot.lua:279: in function 'new'

ammo-loader/lib/createdQ.lua:252: in function 'tick'
ammo-loader/lib/Handlers.lua:201: in function <ammo-loader/lib/Handlers.lua:197>

Not sure what the triggering even is

Just spotted this is a duplicate bug..

I just uploaded 1.1.3 which should fix this issue. I'm working on other bugfixes as we speak. Let me know if you still have issues!
