Hi guys,
so I have really been enjoying morroblivion so far, i've run into no bugs on your end (had some trouble with OBGE/OBSE/Steam cooperating, but nothing to do with morroblivion), and the updated oblivion engine has really breathed new life into morrowind for me.
Today however, I am running into a very persistent bug...I am in Balmora, just about to reach level 2 (exactly 12 restore stamina potions away, to be exact), and every time I level up the game instantly crashes. I have realistic leveling installed, but have tried it both installed and with it removed and it still crashes. The crashes occur immediately after I here the level up sound (with RL, this is immediately after exiting the inventory after crafting, with vanilla leveling it happens just when I am waking up from the mandatory "leveling nap"). Other than realistic leveling, I also have the following mods installed.
Unofficial oblivion patch, supreme magicka, stealth overhaul, protocolled dialogues, silent voice, the uncapper, OBGE with some extras, streamline, and script optimization.
I have tried disabling everything except the oblivion and morroblivion masters and the morroblivion_ob esps, but it still crashes. I have also done the oblivion.ini fixes (the ones for post-patch 1.2 bethesda server thing).
Any help would be greatly appreciated, thanks again for the awesome mod!

Do you have any mod that
Do you have any mod that replaces Data\menus\levelup_menu.xml? If yes, try deleting it.
Also, post your load order.
