Yes it was maked with ultimade mod maker (I know because I am andreighinea1 but I maked another account to response because I reached the maximum activity in this tay)
Sorry but UME is severely outdated. Newer version of GDT use a new mod format which is incompatible with UME mod format. Use JavaScript next time.

The thing is, not many people use UltimateLib anymore. You mod will not work without it, and you are pretty much adding to the list of non-working mods.
OK I know some things to how to make mods in javascript but I used UME because it was more simple. The next update for the mod will be in JavaScript. Thank you !
