For the record, I didn't find anything wrong, I can only guess it's sheer RNG.
Does anyone have the mod updated and already compressed to pass because I try to do this and it gives an error
Compressed? It's less than 20MB, are we in 1994? Make sure you select the specific version you want and just download that one, don't download the entire folder.
Is there a wiki for the HGG version? Would be really helpful.
No wiki, at least that anyone contributing to the mod is aware of. If something confuses you, please say so and I'll see what I can do. If something is designed in an unclear way, I may make changes so the game better telegraphs what to do.
If you want more general information, the Credits button on the menu is a fairly organized list of what /hgg/ adds. There are separate buttons for showing credits from vanilla and revamp, so it's clear where each thing comes from.
For some other general things,
There is a lot of content in the swamp with the moth girl.
There is a lot of content in the bog with the zombie girl. (YURI FOCUS. But if you don't mind a "dead fish" style, you have sex options as a non-female, and you do get most of her other content too, just without a romantic side.)
There is a lot of content in the deep woods at night, which can lead to a dungeon.
There is a lot of content in the Volcanic Crag, including a dungeon.
Fera has more content. This can result in 14 new spells, but using them toggles
off Black & White magic and you can only swap between them at camp. Also the boss fight is absolutely ball-busting and I'm remastering that quest in version 1.8 (which isn't soon, there's 1.7 next and probably minor content updating between that and 1.8)
Telly
Check the options menu for fetish toggles.
Have kids with your camp companions. Not all have much to them, but usually at least something. Izma's kids have the most. Helspawn is fuckable.
Pay attention to what's written. Usually it is meant to be enjoyable to read, and sometimes useful.
Explore the forest after surveying and clearing the land for your cabin. If you do not have a toolbox, you'll be able to get one for free this way.
If you're carrying the beautiful sword when you kill unique demons, it will get +1 attack permanently. Equipped or in inventory.
That said, recruiting Ceraph has a lot of scenes, and the sword is pretty powerful in general, so you shouldn't feel like you have to kill them all.
But it is fun to kill them all.
Clear the factory early. Even in vanilla, you'd be surprised how much content is disabled until then. Like Dominika giving you the spell blade (or that was requiring meeting marae, I forget, but meeting marae is needed for the factory so still works.)
Have fun.
