In my map, I am using HotS dependencies, but I wanted to have back the WoL-styled World tooltip (white-colored font except of brown), so I cloned the "HotS_WorldTooltip" layout and replaced the text style value by the one I found in "WorldTooltip". So far so good, works properly, no errors.
But now, I transferred that new asset into a mod file since I want to use it for multiple maps. The fix does still work, BUT everytime I test the map, i get the following error:
Nope, it is only specified in the mod. Is everything with the code alright? I have pretty much no experience with custom layout stuff I just copy all the stuff together that I need to overwrite the old files.
EDIT: Ok, looks like it actually WAS specified in the map... Although I had deleted the maps entry of "TooltipFix" in the UI editor before, there was still an entry referring to that file in the "UI\Layout\DescIndex.SC2Layout" file that decided to stay. Now after I deleted that one the error seems to be gone.
