I added this mod to a server of mine, and me and someone else were near a group of capybara, when suddenly both of our games crashed. Upon further testing it appears that the game will instantly crash whenever they go into water, and then the world/server is unopenable from then on out. We do have a few other mods, which include origins, pehkui, figura, sodium, iris, simple voice chat, xaero's world and minimap, appleskin, decorative blocks, and extra origins. This also occurred on a singleplayer world, and with the newest version.
Here's the crash report:

---- Minecraft Crash Report ----

This appears to be a problem with Sodium so I'd potentially drop on over to their repo and report it there
