Found info that may help our 'placing' issue from multiple mods. Sounds like you just have to Re-DL what mods are ahaed of them in the load order until you stumble on the offending bad files.

- I cant place any structures, I get the green ghost structure but when I click, nothing happens
One mod in your modlist is not correctly updated, causing all mods after it to be unusable too. Just update the mod if you can find which one is causing this, or update every mods.

Enjoying the server, the people and the mod mix. I threw this together on waking. If anything needs changed let me know, and add it to your infomation post if it helps.
