Trade station crashes people in render range if a Flabebe is traded, tested it 10 times, crashed the 6 people who lived near it including myself.
Checked it on a mohist forge server for 1.16.5

Hi there - we need more information, please!

Server logs: latest and debug
Client logs (not from all 6, maybe just 1 or 2 lol): Latest, debug, and crash

Thanks!

I was able to confirm this myself, using the official 9.0.2 curseforge modpack. Adding a flabebe or any of its evolutions as an offer in the trading machine caused the client to crash. I also reproduced this on our testing server, and both me and my trade partner crashed - though nobody else was online at the time to confirm if all players online crash. The server itself remained online, only saying that the crashed players had left the server.

Passing this to internal now, thanks!

Can confirm this still occurs in 9.0.3. One of our developers suggested this is caused by a pokemon with no default palette, and I confirmed that this crash was reproducible with a vivillon as well.

Confirmed fixed for an upcoming release

Resolved by 9.0.4, thanks for the report!
