I have found the issue that is causing the server to constantly crash. It's related to the new bag and warehouse slots and until I can spend some more time researching a proper fix (been at this all damn day and evening), I have had to disable the 3rd extra inventory bag and the 2nd and 3rd extra warehouse bags. This leaves you with the same amount of warehouse space as before (100 slots max) and an extra 50 inventory bag slots (150 max).

Any items you had stored in the 3rd inventory bag or 2nd and 3rd warehouse bag can be found in your Giftbox.

Seems there was a good reason the Iris devs didn't put in extra inventory slots eh. lol.

NOTE: Don't panic when you see your items with no cards/enchants in your Giftbox. Move them into your normal inventory and you will see them again
