I just wanted to know whether I'm doing something wrong or whether this is just incompatible with this mod.

I'm using this mod http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1194812703 for some island chains and I especially like it to have a big island in the middle with two or three connections. Combine that with zombies or other events and there's no way to flee but also a good deathtrap map.

Now everytime I'm rerolling it seems like the previews are VERY inaccurate. I tried changing several options, even used "Configurable maps" to try to come close to whats generated but it is always off. Is there a reason for that or am I doing something wrong here?

This is my modlist: http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=1220744602

I really hope someone can help me with this to find the perfect map!
