If this issue is never resolved, here is a work around if you are able to change your gamemode and gamerules on your server. Luckily I was playing on Realms and could rollback the server a few minutes and re-approach the Mansion.
To stop fires from starting/spreading: Before approaching a mansion type /gamerule DoFireTick false
Switch to Spectator Mode /gamemode 3
Now you are free to fly below the mansion and all area the edges to check for lava. Switch to Creative Mode, /gamemode 1 and remove the lava.
Mojang, please reconsider this as an unresolved bug. I just ran 20k blocks and was wondering why my game FPS dropped so much. There were two lava pools under the mansion. No way to stop it without modifying game rules.
