I think this mod is incompatible with "Assembly combinators", it crashed when picking up the cube from the ground.

55551.051 Error MainLoop.cpp:1468: Exception at tick 7849060: The mod Assembly combinators (0.6.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event assembly-combinator::on_pre_player_mined_item (ID 15)
__assembly-combinator__/script/events.lua:15: table index is nil
stack traceback:
        __assembly-combinator__/script/events.lua:15: in function 'cleanup_entity'
        __assembly-combinator__/script/events.lua:24: in function <__assembly-combinator__/script/events.lua:23>

I am going to mirror the report on the mod mentioned in case the creator wants to fix it.
