Charisma was mentioned some time ago by Patrons for this version, I'm not sure why it went on this long without recovering, but its possible its intentional, as 1c is impossible even at 1% It could be getting reworked, similar to intelligence/quality/item stats.

Customer stack can be removed with save/reload, but its being caused primarily (might not be solely) by Customers who request shields (or more than 1 item)
when They get one item and then "wait", the game has gotten confused, the waiting isn't the sign of that, but for some reason, it has started to think the "first customer" is ready to leave, and when you dismiss the shield customer or complete his request a "second customer" is ready to leave, and "both customers" are leaving - So the game sends in a new customer so the game sends in a new customer.....
and if you do another shield customer  - - - So the game sends in a new, a new, a new customer.

Another shield - new new new new customer

and another 30 shields newnewnewnewnewnewnewnewnewnewnewnewnew~~

Infinitely. So don't even give shield customers anything and just dismiss them, and you should be good, for the most part.

The same, almost, can be said for Sword "specific" customers.

The ones that specify guard, blade and grip they want for their sword
These guys will currently spawn guards if you hold any item that doesn't match their order, and also has a guard, that isn't stolen, btw, stolen and not items don't count. but any item they can detect, that is wrong, will cause the issue.

So if you avoid these two, most problems will be resolved.
(the latter problem hopefully is already resolved)
