Does someone know which downloadable set will replace the Forest set?

I loaded multiple of things from this site and I liked them. But i noticed two problems in my Movies after that. The Original Rural: Forest set was lost and the othet problem is that it's not giving me to add slabs to my studio anymore.

Anyway you are OK without the slabs but does anybody know which downloadable set replace the original Forest set. That would help a lot of my doing!

Well, the origin datas of the forest set are called: set_landscape_forest.(ini and msh).
You should look up if there are files with this name in your data folder and delete or rename them so that the game isn't able to access these files.

Where did you try to place the stabs? On the original studio area or on the extendet area? If last so there's no chance. You can only place sets and buildings onto the sand of the additional area, no weadow or stabs.

Ok thank you. Maybe it was extendet area. I will try this.

And if it doesn't help to delete the named files or if you don't have them in your data folder then your folder is damaged. The only way to use the forest set in that case is to install the origin set as mod.
So this folder is the origin forest-set: www.mediafire.com/file/tifrh1d92d9nbgm/forest+set.rar
Just download it and install it into your data folder as any other mod, too. It will appear with the name: set_landscape_forest in the game.
