Thanks for the quick reply! Realized I was using 1.5.0 not the newest 1.5.1
Going to update and see if I still run into the same issue, but to answer your questions below:

* Does this happen with a certain variant? or with any of them

Yes, seems to only be the Red/Black/Yellow normal sized snake.

* Does the log output anything before crashing? Something like "Couldn't find rattler flag in ENTITY_DATA" before crashing?

Didn't find it, but I've attached the output just in case you'd like to take a look.

* Just to verify, this worlds were created with the latest version, right?

World (1.16.5) was created with untamedwilds-1.16.5-1.5.0.jar

Update:

Did a clean install with untamedwilds-1.16.5.1.5.1.jar without the video setting adjustments above and it crashed upon punching an orange snake. Same error output as before

Just pushed a hotfix that should hopefully fix this

Thanks, all good so far! Appreciate it immensely.

Playing on 1.5.2 and it crashed once when punching a snake, but seems to be fixed now.

Appears to work for me. Thank you very much!

Edit: Scratch that, it works sometimes, but me and my friend just punched a black snake and both crashed.

Same here - I have crashed again with the new version as well, and a new world created

Snake crash on rendering - do have optifine - v 1.5.0.

I'll upgrade and try again, just posting this in case it helps track down some issues.

Not as bad for this snake time. Happened when chopping the red, yellow and black with iron sword.

I didn't even see the snake this time - both this and the last was 1.5.2.

I am not able to replicate this issue, albeit it should be easy to fix

A couple questions, however:

• Does this happen with a certain variant? or with any of them
• Does the log output anything before crashing? Something like "Couldn't find rattler flag in ENTITY_DATA" before crashing?
• Just to verify, this worlds were created with the latest version, right?

Pushed a new version which should (again) hopefully fix this

Thanks. I have played it on a server and it seems to work OK. I spawned in a few snakes using the spawn eggs and it didn't crash when I killed them or punched them.
Being incompatible with a world generated earlier sort of sucks.
Quick question, what happens if I turn snakes off after world generation? will they no longer render in and we will not encounter them or is the config only changing world gen settings and once generated that's it?

Uhhh, the disclaimer about compatibility only applies to pre-1.5.0 worlds, you are good to update between 1.5.X worlds (the ones with crashing snakes), the worst that may happen should be existing Rattlesnakes not rattling

Will close the issue tomorrow unless someone reports further issues
