Alright, it's time to address this, because I can't find a single thread, forum, or notation talking about this to date so far except for one thread here on Mmowned where no one really gave a shit because the poster couldn't explain the issue well enough.
So, here's the deal. Currently with all ArcEmu WotLK revisions, if you go over 50,000 HP on a character on a NON-GM account, you will get permanently D/C'ed when trying to log on to that character. There is absolutely no work-around except to a) not go over 50K HP, or b) upgrade the account to GM status.
I run a private server that features custom items from quests, drops, etc. The custom gear we have does not have like 10000 STM, but it does have a little more than the Blizz gear as it gets more powerful. A lot of players are now getting to the point that they are at or near 50K HP.
We're tired of telling people to donate for GM status to get around the bug (although this ordeal has brought us a crapload of donations lmao). If anyone has any clue or any ideas whatsoever how to get around this, please state it in this thread or send me a private message.
Don't flame, either, please... keep the "DIRRR THAT'S WHY YOU SHOULD RUN BLIZZLIKE REALMS ONLY" out of this. For the record, it's quite possible to achieve 50,000 HP with retail-only gear, so it's in everyone's best interest who uses ArcEmu to figure this out.
