minecraft freezes at saving world

[ninkynonk]

In MultiMC, with a Minecraft 1.16.5 instance (no other mods), and any Forge for 1.16.5 installed, launching the instance offline with a changed player name (via the MultiMC player name box that pops up) causes Minecraft to freeze when I later try to "save and quit to title" after playing.  If I uninstall Forge from that instance then saving works as normal without freezing.

 

Also, launching a MultiMC Minecraft instance offline with a changed player name and with Forge installed doesn't show the changed player name in chat (it shows my main account name), whereas if I uninstall Forge and launch the instance offline with a changed player name, the changed player name does show in chat (which is how it has always worked).  

 

This doesn't happen in an older Minecraft instance, for example in an instance of 1.7.10 with Forge I can change the name and it shows the changed name in chat, and the game also saves without freezing.

 

I don't know whether this is an issue with Forge or MultiMC but since MultiMC seems to work as expected without Forge installed I thought I would post the issue here first.

Hi, thanks for replying, launching offline in MultiMC and changing the player name is an option in MultiMC and has always worked before with Forge and mods (usually 1.7.10 mods).  When my daughter plays on my PC she wants her name displayed and not mine (xrys) and launching offline with MultiMC allows this.  We only ever play local LAN worlds with my other daughter.

Oh, sorry, I thought MultiMC was a legitimate launcher, I've found nothing else as useful when playing around with mods.  I guess either she will just have to get used to having my username or I could revert to the last time this worked which was 1.12.2.  Thanks.

I won't drag this on any further than this, I realise this is not a Forge issue, but from what you know of Forge, do you think this issue could be corrrectable by a change to MuliMC, or have there been fundamental changes to Forge / Minecraft which would make this unlikely ? Thanks again for your help.

I just ran it, the debug log is above.

Ok, that is odd,  whatever is happening is right at the end because even though the game gets stuck at "saving world", the world does actually save the progress, but the instance has to be killed manually. I will ask MultiMC if this is something they can look at, I may just have to live with it though, thankyou for looking at the issue.
