Many users have reported they have lost slots (around 8) on all characters and storages.

Some users also reporting they have lost weight as well.

Not related to value packs at all.
Some people speculate it could be todo with the packages but haven't seen enough evidence to support it fully as of yet.

EDIT: @NewsBlackDesert: Yes, we are aware that select players are noticing a reduction in inventory slots/storage (typically 8 slots) as well as missing weight. We're investigating cases as they come in and will report findings as they're confirmed. Thank you for your patience! -CM Tiny Nose

EDIT EDIT: I relogged after the patch just now and that fixed it.

Yes, can confirm. i am missing slots in every storage and in my inventory. noticed this after refreshing my workers, who would not restart their work, because of full storages. and checked it then. its not because of missing VP. It already ran out last week in my case.  So, i cant think of a reason why there are less slots than before maintenance... about weight, i am not sure,either. i think i am missing like 6 lt. playing on EU.

Me too i do miss like 8 inv slots and around 60 Weight limit.

Definitely missing some slots on both Inventory and Storage (maybe 7ish?).  Not sure about weight though.

Same here, I'm also missing inventory slots and weight

Also missing storage, inventory slots and weight limit across all characters. Not sure exactly how much but my storage and inventory are now max and over the weight limit and I distinctly remember they weren't before. Not sure if anything else is missing tbh since I didn't take screenshots. I bought the original pre-order conquerers package if that's relevant!

Missing character and bank storage and weight.  Game is unplayable.

Not missing any slots but I do miss 49 weight limit.

Also not missing slots but am missing roughly 100 weight
