When I tried to use a limited barrel in an already established world and SS system, no matter the tier or material, it is always set to a 32x stack multiplier, whether it's copper, iron, or even netherite. It doesn't even matter whether it's the single, double, triple, or quadruple slot limited barrels, it always has the 32x stack multiplier. It's even in the mod settings, every multiplier for every limited barrel tier stack multiplier is set to 32. SB is perfectly fine, it's SS that has an issue with its limited barrels. I'm not sure whether SSiM has the issue or not, but I'd imagine it does, seeing as how it probably uses the values from SS to govern the values for its boats and minecarts with limited barrels. I'm no modder, so feel free to correct me if I'm wrong.

Edit: I forgot to mention I'm using Forge 1.20.1

I am definitely seeing correct multipliers so I would need more info. Also you want to check the config to see if the modpack maker has perhaps changed the multipliers

I made this modpack for my own use, I never touched the values of SS, so, as far as I know, they should be the default values. I'm using almost every Sophisticated mod available (except for the VH pouches, because I'm using Forge) and afaik, the problem arose with yesterday's SS Forge update on 1.20.1.

What version are you on and have you checked that the confi shows different multipliers for different tiers?

I did check the in-game server config interface and it shows that every tier's stack multiplier has been set to 32x, but the file shows the proper multiplier values for each barrel tier in the server config folder. Shouldn't the in-game server config interface use the same values that the file contains? I'm using mod version 1.20.1-1.3.42.1146 and Forge version 47.4.0

Just checked in game in 1.20 and I am seeing correct multipliers in barrel gui. Not sure what mod you're using to show the in game server config as sophisticated storage doesn't provide that functionality, but from your original message it sounds like you're seeing that multiplier on actual barrels so it's probably showing the "correct" values. I just have no idea why for you specifically it would set all of them to 32x. Perhaps some other mod you have in the pack is messing with the storage configs. Are you able to recreate this with just sophisticated storage?

Also when you say file is showing correct values, are you look at the one in that specific world save's server-config folder?

It actually corrected itself after a relaunch of the game. I have no clue why, but it's like everything tech related, "turn it off and back on again, and it will normally fix itself"

And I haven't been able to recreate it since, so this thread might as well be a closed issue.

And yes, I was looking at the server config files. It's a singleplayer world, so I can check the files with ease.
