If you are using Reaper7's UI-Boote v4.14 MOD and my Equipment Upgrades Fix MOD.
You will want
Equipment Upgrades Fix v1.4 Compatabilty for UI-Boot V4.14 MOD.
Or you can just use Reaper7's version of the "
Page WeaponsAndSensors.ini" file located in the
data\Menu\Pages folder of his MOD. If you do this the only side effect is that some equipment items will not have images on Mechanics Upgrade Menu when in the Bunker.
