Is the mod manager functioning properly?
It seems like you download the mod, then when you install it, it simply copy the files so you end up with both the files in downloaded mods aswell as in _mods, effectively doubling the file space it takes.
Enable auto deleting of archives after install in the options. There is also a trash bin icon do delete all currently installed mod archives.
I have a hotfix coming out soon to warn users about this, the newer versions also default this to true but its not retroactive.
So I have not had the time or energy to comb thread through this thread since the release. So bugs posted here have gone unnoticed, I have been fixing stuff as posted on the discord only.
I am now aware of issues installing mods on Linux, Mac and Android. If you are on one of these platforms and have some technical ability please message me so we can work together to fix them.
Quite a few issues I have noticed such as "defined twice" errors are caused by have copies of mods, likely from installing it manually and with the mod manager. The only way to solve this is to delete one of the copies, preferably the manually installed one.
A couple mods had incorrect mod ids I had to change so if you downloaded the old version you will see a duplicate and can also cause this issue. The two I know for sure had this issue was wirox's Geisha Kyd expansion and ET's Abella Danger expansion.
I will try be more on top of bug reports here but its a lot harder to get details in a forum environment than directly through Discord.
