Fixed the mentioned issues. Also gave all other objects in the cell a quick check, and moved a fork and two marshmerrows that were hidden within the bookshelf as well as a bottle on the desk that was a bit close to the edge.
Brings the services offered at mainland Temples a bit closer to vanilla. Now, the players won't have to return to Balmora to learn Almsivi Intervention. There's also a few other minor fixes.
Tholer Andas' forcegreeting is called from two scripts: Andas battle script (when you're close enough) and vault guard script (when they're attacked). GetAttacked check in the vault guard script may infinitely trigger Andas' forcegreeting because it doesn't have a variable check or anything like that. Forcegreeting in Andas battle script, on the other hand, is wrapped into a shoutonce == 0 check and sets it to 1.
Two NPCs in Map 1 and Map 4 are equipped with the Silver Sword of Paralysis from the Bloodmoon expansion. This sword is inexplicably more powerful than its Daedric counterparts whilst providing a paralysis effect. This sword is also found in the TData leveled list for one hand long at PC Level 15. A fix for data has been submitted on Github, this is for the mainland file itself that fixes the NPCs and gives them Silve Flameswords instead.
