Vanilla Bug - Unsolved Excavation Pit upgrades to Ceramic Kiln instead of -secret-

When trying to upgrade the Excavation Pit to

Crystal Cave

, it upgrades to Ceramic Kiln instead.

I have the latest versions of 3-in-1 + conquest + mega pack installed.

What you want requires discovering a secret item in another plot.

If you mean

the glowing crystal in the iron mine

, I already have or I wouldn't have the option to upgrade to it.

Strange, the upgrade works in a different settlement, just not in the one where I actually found the

glowing crystal

which seem rather counterintuitive since the message you get when you find it is that the settlement must sit on a deposit of it.

Plots upgrading to the wrong one can occur if scripts are backed up when you attempt to do so and also view one of the other upgrade options and cancel it.

To ensure a plot upgrades to the correct one every time, especially something important like this where if it goes wrong, you're out a lot of time, check your inventory for any building plan objects before you trigger the upgrade and drop them on the ground if you find them. Then when you select the upgrade, be certain not to select any of the other options first.

Fixing this permanently will require a pretty massive rewrite of SS that will invalidate a lot of old add-on packs, so it's unfortunately a problem we're stuck with for the foreseeable future.
