Couldn’t find it in the patch Notes, but it seem a lot of Stack sizes seem to have been reduced by up to 90%.
Things you could Stack to 1000 now Stacks to 100. Is this intended or a bug?
That, combined with the reduced Inventories (Fishtraps, Workstations) and the inflated numbers of Workstations needed (which take way too much space)… do you want us to build walls out of Chests to store our stuff and making Bases even more bigger?
And why is the Vanity “Mirror” a huge Workstation, instead a real Mirror you can just put on a single Wall tile?!
In order to determine what is and isn’t a bug, and what could be a mod change, you need to post a viable amount of information in order to figure that out. But you just “some things”. What things?
It may not be a stacking mod but a mod that amongst other things modifies stacks. It sounds like you are getting the base game values now and your game is working as intended. It might be due to a mod that has been removed.
