No... I'm doing fine (I mean that any of YOUR maps, from Legacy of Shanti → Temporal Paradox → In Search of the Rune Sphere → The Path Home, conflicts with Grover's Expedition, but they don't conflict with each other when they are all together in the maps folder). Grover's Expedition should be the ONLY one in the folder, besides the mandatory EWA_XL.h5m for those who have the EWA mod. It's just strange.
P.S. I really enjoyed the map, although it's tough with the mod (I'm playing on Veteran). I defeated Necropolis without any losses – counter-spells are effective, plus a set of 3 speed artifacts and Darkness (slows down). I have 2 tomes and a tear left, and a demon remains. I can't figure out where to get the purple key (I suspect it's in the Light tome). Of the secondary objectives, 10 Thunderbirds remain to be collected. The map is completely cleared (except for the black spot near the center with the Haven guard). Question: who has the purple key? FrenzyFireFly is also puzzled by this question?
After the prophet, after 5-7 days, Glen should attack the player. After the victory, the path in the center of the map will open.
