Printer crashes Minecraft during printing, whether observed or not, while printing any photos of Pokemon onto cards (tested first with a Shiny Galvantula photo onto a Holo Rare and then with a normal Gastly on a Psychic Common), with the following error:

The game crashed whilst ticking block entity
Error: java.lang.ArrayIndexOutOfBoundsException: -1

Energy printed fine after removing the photo before the game could crash upon reload.

Opening Base Set and Jungle booster packs, but not Fossil or Team Rocket, caused the following error:

The game crashed whilst rendering screen
Error: java.lang.NullPointerException: Rendering screen

I also haven't been able to buy booster packs from shopkeepers, view essences dropping from defeated Pokemon (I still receive the essences), or craft blank cards.

Another fatal crash, NullPointerException while updating screen events after attempting to move the binder item while the binder was open.

Thanks for the report.

Do you have the full crash reports for these issues? The traces and mod list contain the info we'd need to be able to diagnose this, the errors by themselves don't say much yet.

Tried to post a crash report and got sent to a Cloudflare "you are blocked" site page for posting it. Is there any other way I can give you the crash logs, or am I doing something wrong? I have all three of them (weirdly enough, only one of the logs actually refers to my world by its name, the other two call it MpServer, not sure if that's normal).

Sorry for the late reply, only just noticed this had a new post on it. I'm not entirely sure about that error, but putting the log contents into Pastebin and posting those links may do the trick. Alternatively, the Discord has a #log-upload channel and a #general-support channel that people may be able to help in.

EDIT: Sorry for any notifications just now, batch ticket update didn't go too well.
