Hotfix v0.8.15

- Fixed crash when an item in the inventory has undefined/null quantity. In such cases, a full stack of items will replace the bugged item slot.

Regarding the above fix
- It allows players who had the crashing bug to continue playing on the same save.
- The cause of the inventory quantity bugging out in the first place is currently unknown. Once it can be replicated, I'll fix it too.

Thank you for playing RS!
