The mod Inserter Configuration (1.0.0) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event Inserter_Config::inserter-config-drop-distance-adjust (ID 224)
real number expected got nan.
stack traceback:
[C]: in function 'newindex'
__Inserter_Config/control.lua:128: in function 'set_arm_positions'
Inserter_Config/control.lua:504: in function <Inserter_Config/control.lua:470>

This crash is caused by using Miniloaders and pressing F on any of the loaders, be it the powered ones or the chutes, if anyone finds out a work-around for this bug please post it here, if I find anything I will update this thread too.

Just tried it, and a little work-around is to just remove the hotkey "F" from the inserters configuration mod controls menu, or bind it to a key you are not prone to accidentally pressing
