There is a crash associated with other mods and this one, caused by a wrong empty-sprite
They are:
1: the path is incorrect, meaning the file does not exist (the obvious one) Construction_Drones should be warptorio2_expansion
2: the tf_util.lua file edits the util object, so the broken filename is spread to anything using util. It should instead use table.deepcopy(require("util"))
3: the projectiles.lua file doesn't declare util as local, so overwrites the util object anyway. To fix this it should be local util = require "data/tf_util/tf_util"
