Maybe because some mods are outdated/broken. If you're modding a game you should be aware that no one can guarantee that all of them will work, and especially if all of them are compatible with each other. You'll have to manually disable each mod one by one and try running the game each time to find the culprit or you can check the description of every mod you're using to see if they're updated to fit into the latest version of the game, or if there are any recent comments about it being broken.

I'm going to make a bold assumption from the very vague information provided, and assume that you're trying to get YAML running, and the mechlab looks like vanilla?

You'll have Simple Mechlab enabled (disable via mod options, or from the main menu checkbox)

Or didn't enable the mods in the in-game mod manager.

"Just don't mod the game"

You must be new.

It is a very common occurrence in this forum to post about issues that after what seems to be extracting teeth, boils down to

User error
User has outdated mods
User has a mod conflict cause they didn't read the mod description
User has not investigated the options in game or in mod.

HK's analysis was correct

"User has outdated mods"

If I had a dollar every time I saw that as the cause of "mod not working" I wouldn't need to work.

Your reply is so dumb you should've just refrained from adding such a useless comment here directed solely at creating an off-topic quarrel with me.
