When entering Gormoro Grotto, the player is spawned so high up that one is looking out of the shell into the void. This is just a visual glitch, but nevertheless the doormarker should be lowered to remove this problem. The coordinates entered are interior coordinates.
During the quest "My Daughter's Keeper", Edryon is supposed to be sleeping from exhaustion when the player finds him. Yet, he is standing up. It looks like his script, TR_m3_q_6_Edryon, is not working as intended.
Dunveri Rodrun of Ouada He is probably meant to be a caravaneer since he is on the gang plank to his ship. He does not offer the "Travel" option. His greeting includes: "Care to see the sights? Where can I take you?" His "trade" option says: "I'm a shipmaster. I can transport you by ship to various destinations for a modest fee." His "destination" option contradicts that: "I transport wares from Tel Ouada to many places on board my ship 'Wave Render'. No personal transports, not even for a %PC_Class%.
There are several green plants in the Mansurabi tunnels. No sunlight can reach here, so these should be removed. The plants in question are flora_bc_fern_0x and flora_bc_moss_0x, and I don't know if the Red Lichens should be allowed in caves either (I have never encountered them there in Vanilla at least). At least one of these is present in each subinterior except the Lava Tunnels.
In some of the high-altitude lakes and ponds in Mephalan Vales, the fake water is placed atop terrain using a grass texture. I don't think the grass would survive very long in these conditions, so it would more logical to use a mud or underwater texture. This would also prevent groundcover mods from placing grass under the water. One example of this is in the lake stretching between (28,-14) and (29,-14), but there might be more occurences.
During the Mages Guild quest "Investigation at Fort Windmoth", the player is supposed to bring up the matter of Francine's arrest with Arvs Rethrari (through the dialogue topic "got arrested"). He then responds with forcing the player to pay her bounty of 5000 gold, simply because the player is sent by the Mages Guild to investigate the matter, and then refuses to explain what the arrest is all about. Fine, he is rude and corrupt, but he acts like this even if the player has a superior rank in the Imperial Legion (even against the Knight of the Imperial Dragon!).
Circus Leonos's first quest in Akamora's Fighter's Guild questline does not have its quest name displayed in the journal. The Quest Name flag is simply not set.
