Whenever I move to another dimension on log in all the cyberware goes poof and isn't functional, to fix it I need to use the surgery chamber in that dimension without doing any alterations. Also it sometimes un-equips some of the cyberware when doing so which I'll need to re-install.
Not a gamebreaking bug but quite an annoying one since I need to lug around a robosurgeon and a surgery chamber.
Maybe a conflict with another mod since it hasn't been reported before?

Minecraft 1.12

Is anyone else having this issue?

I've not seen this myself but I'll be honest I tend to avoid going to the end which is where most of this kind of issue can stem from. It's definitely worth poking around.

Are you supposed to lose it upon death as well? Would make a little sense. Seeing as how some forms of teleportation could effectively create a new instance of the 'player'

I'm also using everlasting abilities, so some of them are hard to notice.
Though it doesn't grant me quite the same armour....yet.

Well I started a new world with a different mod setup and newer version of forge and it seems the issue is solved though I'm not that far with cyber stuff. I guess it's a compatibility with some other mod but the mod list is so different that finding what mod was to blame would take forever.
