When the Prismelter building is placed in a lightning collection area that includes a native Fulgoran Lightning Attractor, the game either hangs or crashes.
When the game crashes rather than hanging, it raises the following:
The mod Iridescent Industry (0.3.1) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event IridescentIndustry::on_script_trigger_effect (ID 169)
IridescentIndustry/control.lua:39: attempt to index local 'recipe' (a nil value)
stack traceback:
IridescentIndustry/control.lua:39: in function <IridescentIndustry/control.lua:1>
I would guess this is because the player-built lightning attractor/collector is producing "lightning" via some recipe that the native Fulgoran attractor doesn't have, but I haven't checked in the mod source to verify that.
