The simplest of modding questions

[zig_zac]

I want to change stats of a unit in EB, not very ambitious project, you may notice. Yet, apparently, it's above my skills.

I started by editing rtw/EB/data/export_descr_unit.txt, didn't help.
The game edited it back upon start. So I marked "read only" option in properties - now the game won't start.
I also edited rtw/data/export_descr_unit.txt, which didn't help either.

What do I do wrong?

I will be grateful for help, as I plan to have great fun with this changes.

Hello Zic_zac, welcome to the .Org and to EB! ~:wave:

In order to have separate SP and MP unit rosters, the team has created two different export_descr_unit (EDU) files. Depending on what you choose during start-up, the EDU in the data folder is overwritten by the EDU from "mp custom game edu" folder or the "sp campaign game edu" folder. The latter is the one you have to edit in order to change units in your campaign game.

As always, don't forget to make a back-up ~;) .

Yep, it works! It's gonna be fun. Thank you for your help.
