[Area-script] broken trigger-condition in Sunny Hillock

[valky]

(weird things...new game started *uhm* 25/10/2018 and quest was working before)

Once you save/load or buff (area like good hope etc) you seem to trigger the redcaps, which are part of the 2nd attack (e.g. failed diplomacy check) but:
- they are invisible, like not existent but trigger AoO's (perm-combat)
- if quicksaved on map-start and reloading, you sometimes auto-engage and start killing imaginary/non-existent redcaps - works not always, but looks funny
- if you start buffing, you have a chance to trigger the invisible/non-existent redcaps (perm-combat)
- if only saving, you have a chance to...(read above)
-- if mixing save/buff or buff/save (depends on the buff, though)...read above

The whole crap also seemed to be be memory resistant, cause once one of the wicked behavior is triggered - you always get the broken map, even if loaded from quicksave done prior to entering.
Had to revert back to after (yarr!) killing the rill-and-spill resident and re-start the game, just to be sure. Also, and it does sound even more weird, the loading points above the crown (yeah..loading screen) in such a messed up savegame were not going left--right, but rather blinking, like 1-3-5 / 2-4 / full load of all points..then some different constellation.

Furthermore (it's not finished), if you manage to trigger the treant-spawn (including the camera movement stuff...), in the following dialog with the nereid and after beating the diplomacy(LG or LN..not sure..but shouldn't matter) she sometimes fails to cast her portal and engages in combat (you get EXP for diplo solution + trader EXP + kill EXP...)...trigger also/sometimes the redcaps, but attackable :> *yay*

Hmm...what else...what worked and is more or less a broken solution as well:
- I used my 'Rill-and-Spill' save, while on the map...left..traveled to Sunny Hillock, initiated the dialog, did some choice..and left him alone. Yeah, one could only guess, this gives you right away the Diplo-check, which nets you some very serious EXP - the nereid does properly leave the map and restores everything and you don't need to kill the treants.

THe quest did definetely work in 2 prior runs, but I can't remember the redcaps.

edit: cause it was only a quicksave (rill-spill), it's obviously gone :P Made a hard save..but once I figured and got it working...needless to say it's gone :Þ
real hard fail-savegame was 1.4 month before the encounter, so if demanded..I could most likely try to redo that...

edit II: A good example of different visualized loading behaviour'd be windows 10 .. if it loads normaly, I think it only shows 5 points around the window thingie; if update/recovery/critical it shows 6 loading *blobbs* instead - not sure if it's still the case, but friend of mine (not drugs but ADHD noticed)
yeah & you've got tons of loading screens ...
