Until today going through nether portals rarely made me crawl which wasn't too bad but today I suffocated in a wall going through a nether portal, pretty sure this has to do with Ido since it didn't ever happen to me in thausands of hours of playing vanilla survival.

Seems the issue has been fixed on my end. I will be pushing the update once its finished

What other mods are you currently using?

Modlist of my modpack, nothing else should really alter portals tho, mup has some fixes related to portals but nothing that should make you get stuck in them. I was running the same mods without Ido for a while and it never happened, now I notice the ocasional crawling when teleporting and this one time it seemed like I spawned in one of the obsidian blocks.

I am working on a collision check fix update so this may get patched during that
