Description of bug

Hi i was just updating one of my instances (1.21.11 to 26.1) and after it had complete i went to load it up, and nothing happened so i went to look into the logs and there wasn't anything in them i just sruged it off as a strange issue but i tried again and everything and i mean everything just vanished first it was the instance i was trying to load then about 10 seconds later it was all other instances (around 7 others), then it just closed, i tried to go reopen it and it wasn't there i looked in all my files did a whole system search and it was like MultiMC never was installed

I dont think i have any words to say how mad and honestly upset i am as i just had a world ive been playing for 1 year get deleted as well as all my custom instance that were specifically optimised for my game play

I know that there isn't anyway for you to really fix this (as idk what even could of caused this) but i just wanted to inform you guys as i wont even want this on my worst enemy

p.s still gonna use your product tho

Steps to reproduce

I guess updating from 1.21.11-26.1 with sodium + all extra add ons like sodium extra and a whole lot of mods that i would need to give you a list of as idk right now

Suspected cause

Update just recreated the same issues using the sodium plus modpack and doing the same upgrade path (1.21.11-26.1)

did it with just sodium and fabric installed also just deleted its self

ive also tried it with no modpack and all has worked fine

Did a fully system restart before trying any of this

you will have to be a bit more specific as to what you did, theres no code in multimc to uninstall itself

Sorry if i wasn't clear enough what happened was i wanted to update to 26.1 so i did the whole normal upgrade process that iv'e done multiple times before and after it was done updating and confirmed to be on the new version i went to load it up and nothing. I just thought that i might of just not pressed the button or the app need to fetch so files so i gave it some time (around 1-2 minutes) but when i pressed it again the instance disappeared from multiMc confused i look at my other instances to see if maybe it got renamed because it updated and then after i look through 3/7 of my instances they all also deleted them self first the ones i had looked at and then the ones i didn't all in around 5 ish seconds, now i was very very confused and closed the app maybe thinking that it was a bug but i went to reopen it and look at my dock and didn't see multimc there i went into applications as well as did a whole system search for multimc and nothing showed up it was like it had never been installed.

I then reinstalled multimc to well see nothing there obviously, i went through the whole setting up process and went to just load up a new instance ( a 21.11 instance with all mods that were working before the attempted upgrade) and it did the same thing again, mind you this was now after a system restart. I then restarted again and tried it with just sodium and fabric instance, i load up the instance before trying top upgrade played a world for 5 minutes and all was fine but then it came to upgrading and same thing crash the uninstalling it self.

so i did the repeat all over again but now tried with just basic minecraft and that worked fine

But i did also try it with a modpack from modrinth called Sodium plus and that all worked fine and ive been playing on that since and have ben able to upgrade and even tested downgrading and all was fine.

I would love to give logs or anything but as i've said due to it uninstalling and me restarting my system so much there is no logs available to give

If there is anything else you need for me please do ask

if you mean by reinstalled is deleting the app then yes that would wipe all your data #1457
