Right after updating, loading a game that had the mod makes the game crash on load with the following message:

Exception at tick 219: The mod Item Cam 2 (0.8.5) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event item-cam-2::on_object_destroyed (ID 174)
__item-cam-2__/script/state.lua:77: attempt to index local 'identifier' (a nil value)
stack traceback:
        __item-cam-2__/script/state.lua:77: in function 'forget'
        __item-cam-2__/script/events-tick.lua:60: in function <__item-cam-2__/script/events-tick.lua:57>

Woops my fault, nil check made too late. Try 0.8.6

This is fixed now, thanks for the update.
