Plumbing Mod Conflict

[genchadt]

Describe the bug
The Plumbing mod conflicts with Hydrocraft. Namely, water pumps from Plumbing immediately are overwritten by Hydrocraft "water mills" as soon as they are built. There is also a Lua script error that appears every ~1-2 minutes which is pasted below:

function: WeedFarmWorldItemHandle -- file: timetracker.lua line # 243 | MOD: Hydrocraft Build 41 Continued
function: WeedFarmItemCheck -- file: timetracker.lua line # 269 | MOD: Hydrocraft Build 41 Continued
java.lang.RuntimeException: __sub not defined for operands in WeedFarmWorldItemReplace
