This might help with a modding bug(s) after 1.3...

[Chuckles]

I recently re-installed m2tw and un-packed everything ( I got the 1.3 patch from kingdoms) and modded in some units. I noticed there were blank areas (where the units stats are) on the unit info cards for all units when I right clicked on them (on the camp. and battle map) and also other blank areas on the campaign map where text should be. So I decided to delete everything in data/text except for export_units and it's bin file(since I needed them for my extra units). The game displayed all the text correctly after that.
Anyway I hope this might help someone.

This was indeed very helpful, helps the graphical artifacts go away.

Thanks!
