Anyway, thank you all for the interest, and as for the problems with collision and other things that some people are experiencing: It's probably due to some faulty installation (Could be caused by the download not completing, and leaving out some files, always double check that), OR it's a mod conflict, OR a conflict due to newer time stamps on the BSA files after using the official patch.
To re-set the .bsa file date back to the one before the patch, use BSA Patcher. Also, you can try opening the MyMountainTower.esp in the construction set, and saving it to make its time stamp the most recent one. You might also make sure there are no conflicts with other by using Mod Conflict Detector.
