There appears to be a bug with loading your game. It seems to be related to having a wand in your inventory. The character is loaded first but when the wand is put back into your inventory its number of charges is re-rolled, thus throwing off the RNG used for generating the level the way it was when you saved.
Expect this to be fixed and an update to be released either today or tomorrow.
Until then either try to finish your run or if you must save then use up the charges in your wand and throw it and hit an enemy with it to delete it from the level.

ROGUE-FP is a blend of old school classic roguelike gameplay with new school first person controls and perspective. There is no movement grid and no rigid turn system to slow you down.
Synopsis
The Fighters guild has a high bar for entry. They want you to delve deep into the Dungeon of Doom and return to the surface with the Amulet of Yendor. A perilous quest few have completed, for within the dungeon are terrible monsters, devious traps, and mystifying magical items. To survive you'll have to identify the items, navigate the dark labyrinths within the dungeon, and fight your way past the monsters. With enough skill and a decent amount of luck they say it can be done. Give it your best shot!
