Hey there. I actually haven't played in awhile but I'm starting back up again. Still playing 1.7.10 because of Buildcraft and am playing on a personal server/multiplayer instead of the normal singleplayer setup. Running Thermos 1.7.10 1614, buildcraft, optifine, 1.12.7 of the minimap and b1.8.1 of the world map.
I actually mentioned this "bug" several versions ago before I had stopped playing, you had corrected it, but somehow between then and now you either changed it back or it put itself back in. The y coordinate under the minimap shows the eye-level instead of the feet-level. I tried to go backwards through the thread to see if you reverted it back or not but didn't notice any mention of it after you made the change.
Keep up the good work!
