As the title said, the game grash uppon startup. It doesnt load at all.
I was trying to load it by CurseforgeAPP and this dont work. So i came on the website, trying to find the files updates (even the API) but it still dont work.
Can you check this, i love those axolot variant you all made.

Latest Log

What version of MAVM you're using?

It is the one available on CurseForge App: mav-1.2.0mc1.19.2
So i presume it only for 1.19.2 but i was on 19.3
But your Api is for 19.3. I saw this with a couple of mod too. They are available for 1.19.3 on Curseforge but when downloaded (or if we check the version available) they for the oldest version.

My mod has a 1.19.3 version.

More Axolotl Variants Mod (1.19.2 & 1.19.3):

The API: (1.19.3 only):
https://www.curseforge.com/minecraft/mc-mods/mavapi/files/4166341

So I've tried again and it doesnt work. I've download them from the link you gave me and it still give me the same error. If i remove them from the mods folders everything works well.
I cant get a crash log but i got another latest.

withaxolot.log

Edit: i just have another log with only your mod. Nothing else.
onlyaxolot.log

And Both are with Forge 44.1.5

Could you download the new update i've done and check if it's fixed? Thank you for the report.

Seems like that was the API. It's all good now :D And everything work perfectly.

I'd love to have that time and the patience learning coding like that. You did a great job!
Thx And Good luck with the futures update (^^)/
