All of my character names are in all caps after maintenance. Not the hugest of issues but I find it annoying and it makes my character names harder to read on an already not great Lobby screen (sorry, love ya, but it needs some work)
e.g. before PitZerker
e.g. after PITZERKER
EDIT: Fixed now, thank you!
I kind of like it this way
Agreed, this is pretty annoying. MilkMachine? MILKMACHINE. DuncanMacleod? DUNCANMACLEOD. WizzenedGizzard? WIZZENEDGIZZARD. LeapVader? LEAPVADER. OnlyRares? ONLYRARES. HeavensBrethren? HEAVENSBRETHREN. And on and on. I named my characters specifically, using proper capitalization. To have them all essentially ruined by this, while admittedly rather inconsequential, is sad and annoying and I hope it gets fixed/reverted. If people want their character names in ALL CAPS, they can do that, but don’t force it on us without our consent, that’s digital reap.
Agreed, this is quite rough. We could certainly have used all caps if we had wanted to on character creations, I mention for Bodach. I hope this gets fixed soon!
Is Blizzard Diablo 2 Resurrected going to be able to fix the CAPS back to the way we had on our characters names after that maintenance started for half a day
Posted after the last server maintenance:
Well, I’m upset that they didn’t notice what they did to my control settings . . . but until the 14th I am NEBUCHADNEZZAR! 
--at least after the 2 minutes it takes me to reset my controls each time! Jajajajja!

"I figured out a work-around.
Rename your current “Player.ctlo” or “Player.keyo” file to “PLAYER.ctlo” or “PLAYER.keyo”. Basically make the name all uppercase."
You can find these files directory by typing in your character name into the Windows Search bar, and I tested it myself it works great.
It’s all fixed for me now!
