Traveling through portals may cause locked slots to be cleared

[0xf0xx0]

Issue
Sometimes when traveling through portals, locked slots are cleared and moved into unlocked slots. If you have no clear unlocked slots (returning from a mining expedition for example), the items will instead end up being thrown in a small radius around you, potentially resulting in item loss.
I can't seem to consistently reproduce this. Sometimes it fixes itself, other times a quick toggle of the locked state fixes it. I almost exclusively play on servers, but a quick singleplayer test didn't cause the issue to crop up.

increase this value until the problem disappears
don't just put it on max 😉

That seems to have fixed it, and in hindsight feels very obvious xd
Thanks!
