Just a quick confirmation that ver. 2.2 (PE version) of Jara's beautiful MultiMod works fine in both PE and UE installs (in my FrankenWOFF 4.18, for example). Only recommendation is to leave the Orbyx fuel modification "off" if running in version 5.03 or lower of WOFF - since the fuel modification mod. had some tweaks included in ver. 2.2 of the MultiMod that are specific to patch 5.04 of WOFF. If you don't use the fuel mod. feel free to use ver. 2.2 of the MultiMod across various UE and PE iterations of WOFF, for simplicity's sake.
Cheers all,
