Error while running event m-rpg_items::on_entity_damaged (ID 103)
LuaEntity API call when LuaEntity was invalid.
stack traceback:
[C]: in function 'index'
__m-rpg_items/control.lua:800: in function <m-rpg_items/control.lua:743>

The error occurred when I was blown up by my own shells in close proximity to me

Thanks for the report. However, it seems like you used not the latest version... please provide info about which mod version did you use.

(。・＿・。)ﾉI’m sorry~it's the latest version, but I'm at line 685 of the assignment code, and I can change the amount of gold obtained

local getmoney = settings.global["rpgitems_enemy_getmoney"].value

0.21.8
0.21.7
I tested them and they all have the same problem,

By the way,can the equipment bar be hidden? if you buy too much it's long long long ....
Like the Placeables mod

By the way,can the equipment bar be hidden?

Not implemented (yet) as far as I remember.

I published new version, but I have no idea if it fixes the bug or not

Tested and fixed successfully, thanks for your work!
