Yeah I tried ~1000 too.LoadOrder is pretty finicky. you have to set it at exactly the same scope in both mods, and i don't think it affects <UIScripts>. i had so much trouble with it that i came up with an entirely different method to override the tooltip, haha. btw, what do you mean by "very high"? i usually set my mods to LoadOrder 1000, although occasionally i use a higher value if i need to override a specific mod.
A setup that works is:
- My "fixes" mini-mod: 1000
- TCS's tooltips: 1001
- TCS's tooltips modified to use <ImportFiles>
