crashing after taming an equus horse

[rott_n]

basically title. i had already tamed another horse with no issues, so im not sure if it IS connected, but it was Literally the last thing i did before the game crashed, and the crash logs both mention the error being in the jaunt mod. upon booting the game back up and trying to load in, it crashed again.

is it fixable? and is the world saveable whatsoever? id be sad to see it go, i wasnt far in but i had gotten lots of pets, so :[

Welcome to the game and forums!

The answer is...maybe. It looks like you're using the test release of Jaunt, which is more likely to contain issues. I'd recommend trying out the stable version of the mod(make a backup of your world first!) and see if that helps. You'll probably also want to report the issue to the mod author as well, though you may also want to create a test world and test just Jaunt and Equus to see if the issue still occurs in case the problem is actually with a different mod(probably not the case, but doesn't hurt to make sure).

Otherwise...you may want to play a different world for a while and wait for the Jaunt issue to be resolved.

oh wow, thank you for the quick response! 

this would make sense... i was installing the most recent versions of mods in case they had bug fixes, and wasnt thinking of test versions at all. i did as you said, and it worked :] thank you for the help
