oops! I'm sorry and thanks!

@trient: Only addons that are enabled when you create a character are applied to that character.

I applied it during gameplay, but this addon isn't working.
Melinda's event still occurs as a random encounter.
What could be the problem?
For reference, I'm including a list of other mods I'm using.

Godfeaster on the map
Adbenturer Mastery
Starting Prodigy Remixed
Breeding pits Restoration Project
Display class
ZOmnibus Addon Pack
Turn Separators v2
Better Item Description
Escorts Enhanced

oh it was my own fault. i had a conflict with

@Nekohime: What sort of problem are you having? The zone simply not appearing? If you can get a copy of the log file, I can try to investigate.

Doesn't work for me anymore

Mhm mod works fine as of 9th November.

Mod seems to be working fine after the necromancer update

@FlowingLily: It's worked in all my tests so far. The required-version listed in the Addons dialog is a minimum.

Will this addon ever be up to date/does it work with the current version?

@Hypsicratea: No, that part doesn't change; that would probably seriously mess up the quest handling for this quest.

No worries. Glad I could point out something that was overlooked. Thanks for taking the time to look into it and update.

[sound F/X: source diving] ... [sound F/X: forehead repeatedly striking desk] I swear I thought the game engine code checked for that... @caerold: No, Sludgenest and the Volcanic caldera have fixed locations for their zone entrances and don't use the main encounter spot list; that was entirely my stupid mistake. I don't think there's any way to bring back your Hidden compound entrance, sorry; the latest release, at least, should prevent it from happening again.

Looks like this might have been a conflict with "Extra Dungeons" (ensures caldera and sludge on all characters) -- I wonder if it's a case of more side quests existing than predefined sidequest entrances?

Unfortunately this caused the crypt entrance to OVERWRITE the Hidden Compound (Circle of Blood) entrance when I exited Daikara at level 25. There doesn't appear to be sufficient protection to prevent overwriting existing quest locations -- I guess I'm just lucky it didn't do in a more interesting side quest. Note that I had located the entrance before this but not entered the compound when this occurred.

@Xafron Chi: Mods installed via Steam or from te4.org are considered "official", and do not prevent getting achievements. And I've just uploaded an addon that provides similar treatment for the Lost Merchant quest.

Yup. Exactly that one.

This is that dungeon where the elven cultists try to sacrafice that lady ?

You are genius.

Will mods prevent me from getting achievements? And does this exist for other things as well such as the merchant you rescue from the assassin in the hidden trap door?

You know... it seems so simple a solution. Brilliant and simple. Honestly surprised no one did this sooner... Thank you!
