Forgive me if this has already been addressed.

I keep getting this error while trying to buy from other player's shops:

"Oh No! Oops, you have too many items in your Inventory! Clear some stuff out."

This doesn't happen when buying from any of the main shops. And its not a true problem with my inventory because i only have about 10 items and i've already tried deleting things in the inventory...

I was wondering if this is happening to anyone else?

do you have an item in your inventory that is stacked? that counts too.

Check what your inventory number says: xx/100. If it's 100 or more, you won't be able to buy from user shops.

Lol thanks. I'm a complete dork that was it :)
