Hello,
I am aware of this limit and this is what surprises me. As you can see in the steps, adding more items do not cause the problem to happen, but one very specific amount will.
The exception thrown when this very specific amount of items is reached is the following: 0xC0000005: Access violation writing location 0x00000000.
Once I create the new vessel, the total count of items combined across all charfiles is:
177 cargo items
194 equipment items
which is a total of 371 items.
370 will work, 372+ will work. exactly 371 items will cause the account to be unloggable until someone removes one item.
I have attempted this on another account and you can hold 371 items, but with yoda’s account files, it won’t work.
