Posting this here since i don't own the steam version of the game and so can't just leave a comment on your mod.
The land value becoming stupidly high is because you overwrite base game terrain and give them a <WorkToBuild> value, the game calculate Market value using ingredient value, amount of work to build, quality and health modifer so any tile of terrain you overwritten on the map receive a market value.

yes sadly that what i thought was happening but it its no help coming up with a work around

Could the other mod called "ToolBox" by Nif help you with fixing this issue? I've noticed that this caused my wealth to skyrocket leading raids to be ahead of my level.

will have a look see if it can

Any update?

not really i have discovered you can adjust the storytellers if you put it on custom you can skip wealth based strength and set it to days you still have to move pritty quick to get setup for the first raid

The work around is to essentially create a new tile that is a copy of the standard terrain that so when you assign a worktobuild number to the new terrains you are adding it -doesnt- apply it to the already existing land.

yes but doing that blocks the ability to replace tiles of any type thats how this mod used to work and it also makes you dependant on using the mod right now you can turn on or off at any time

are you using other mods that change water ?

Every time i try to place any water terrain tile it instantly crashes the game.

@steak can you give me abit more than that theres proberbly a mod conflict

I have the same problem, placing moving shallow water too long breaks the game

if its crashing your trying to place it under a protected junk item or a wall

Nope it just crashes right after placing it anywhere

what mods are you using one of them isnt getting along one of them must be changing water tiles have you tried changing the load order place this one either top or bottom that can stop conflicts i can place it just fine
