with the knowledge i have i basically have to edit the Meaningufl Upgrades files manually one by one and upload it as a seperate mod. Its not hard to do, just a lot of work.

Ah, okay good to know it is outdated.

However, shouldn't you be able to get the mod ID from the end of the URL, go into the workshop files for Barotrauma, find that ID, then find the upgrades file for it and make a version that would've had the changes from there and here? I just have zero clue how to put it on steam or not have it be overridden to which ever mod I would've put the other's changes in.

No, this is outdated, it was for a version when upgrades were much more expensive, since the game now has much cheaper updates i have no reason to update this anymore.
As for compability with Meaningful Upgrades i have neither the knowledge or the time to make it compatible with other mods and/or keep it updated.

Will there be a version that patches this with the changes made in Meaningful Upgrades?
