My best guess would be one of these mods are misbehaving:
- Advanced Buildings Editor - not made for use in the city, I recommend completely unsubscribing when you aren't using it.
- DistrictStats - hasn't been updated after Industries came out and might affect the same code as the area overview
On another note, Plop the Growables and Disable Zone Check are incompatible and break each other. You should remove one of them.
Transport Line Manager and Improved Public Transport are also incompatible, so again pick one and remove the other.
Prop Switcher and Prop It Up are incompatible too. I recommend using Prop Switcher - while it doesn't support trees atm, it is being updated and worked on, while Prop It Up is abandoned.
If that doesn't solve the issue, let me know. I can at least narrow down what mods it might then be by excluding the ones I use, so you won't have to test all your mods. :)
