MOD updating

[Doktoros]

What is the best way to find out what's wrong with old MOD? I would like to try to update it to work with latest version, but logs aren't saying anything useful (or I don't think it's useful ),

-Any- errors in the error.log file are useful, fix all of them if you can.

Any ideas what the last patch was the mod worked on?

Reason I ask is that the structure of the game has changed over the years. Make sure the folder structure matches that of vanilla.
If the mod is ctd, good places to run diffs on are the interface folder, map folder and defines.lua. Events can also cause CTDs but most often they cause them after you're in game (and the error log is these days pretty good at telling you what's wrong in them).

If your error.log seems a bit useless you might not have turned on debug options
Add the following to launch options in steam;
-debug -debugscripts

I use WinMerge to see what has changed between the base game and the mod then see what needs changing.
