Hello!
I have noticed that when using Ido, the animations are not applied. (Crawling/Swimming, in particular.) As such, whenever I use the animations, they just keep my character standing straight up (as seen in these images.) Is this a Incompatibility with Optifine, or something else?

Modlist is a large one, but here it is.

Broken Animations:

Apologies for the Modlist length, but I needed Assistance.
Cheers!

I can't seem to find any mod that should be conflicting with ido. I recommend either trying the release version and not the beta and if nothing else works id say to test to see what mods could be doing it by removing and adding them back one by one.

Alright. I shall try that. Thank you!

Can confirm that the beta was the reason for the animation error. Thank you for suggestion to change Ido versions!
