One while opening trade menu (crashed right after clicking accept trade in chat):

(Trying to parse null value as integer)

Root cause maybe here: https://github.com/Moulberry/NotEnoughUpdates/blob/06c3c7fcfd8f65e2a30f81626457f4180ea52a36/src/main/java/io/github/moulberry/notenoughupdates/profileviewer/GuiProfileViewer.java#L1101

Maximum is LEGENDARY, but there is also a MYTHIC rarity now. So this maybe the reason it was returning null but I'm not sure.
