@Slovenius Hmm.. I don't know what your problem is. For me, the park is loaded normally and I can place it without any problems.

Are you using thale5's Loading Screen Mod? Unfortunately it doesn't work at the moment. Klyte45 created a temporary fix for Airports DLC https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=2731207699 . It works smoothly.

What does the loading screen mod say exactly?

This is very beautifull park but crash my game out of loading screen mod. Please can you check? One of this asset or this asset has critical error.
