The Rustles sidemod consistently produces a server crash in 8.3 when entering a Rustle encounter. It is reproducible, and happens consistently every time. This crash did not occur in Pixelmon 8.2, running the same exact other mods.

Have you reset the Pixelmon hocon and Rustles config?

Yes, I have. As well as all the external .jsons.

It's a problem that happened to me once, but it hasn't appeared since then. Let's check it out in detail. Thank you.

If you can contact me on Discord, please! I have something to say with you about solving this!
