My friend joined me for the first time in a while, weve had a couple isses (mainly me ((the host)) being able to force respawn when im down) but today we loaded up and she moves fine on my end but my character on her end keeps teleporting, glitching inside objects, and just overall is super un-synced. Never had this issue before, wondering if it was an update that glitched it or if were having a (hopefully fixable) bug. Its only me, all the NPCs move fine. I put in a support ticket, but just incase anyone here has any idea on a fix, i figured may as well see
#Co-op host seems broken? (visuals)

thats just techland coop desync right there, teleporting players, not moving npcs, unlootable mobs, etc
you could try checking your net connection but idk 
there's really no "fix" for this, so your best bet is to hope that coop works correctly
thinking the same thing about connection issues but on her end possibly. Stuff like that could happen depending on how many devices are on the network and if someone is streaming Train to Busan in 4K and have 10 other devices connected to the internet simultaneously, surely there will cause connection issues. I would start there first to see if that's causing it by seeing which device is hogging the bandwidth, then would check the router's firmware for updates, if is UPnP Enabled, ports are in order, and avoiding double NAT, etc. that can cause these issues.
Sorry been busy days, but she actually has less traffic than normal right now, so i dont think it could be that. She did recently upgrade her pc, but i dont see how that could cause problems since everything is better now. Also we found if she host, its still me thats glitchy. Were gonna try again later to see if maybe it was just a rough day for the game or something
desync that's it
Hey, upping this as I have the exact same issue
You meant to say that basically coop is just a russian roulette?
Me and my two friends bought this game to play together
Same problem here. I used to play with my son in crossplay steam/epic on PC. We just can’t play anymore together for more than 2 minutes without being disconnected.
Bit of a late response but if you havent tried lately it was fixed for me and my friend.
Also to this response, there was an update that fixed it for us, unsure if it helped everyone though
