The game it's self is not broken, this update may have made some mods "outdated" if that is the case then clear all your repo mods and remove any outdated mods that you have manually dropped into the mod folder. Just wait for mods to get updated, if some don't get updated then oh well, tis the nature of BeamNG that some mods may not get updated. And also clear your cache as well. Since I cleared out the now outdated mods, the game has been running smoothly for me. I even have been using the new updated CRD Monster truck stuff and the game is running without any issues. Again, just wait for mods to get updated before trying to use them if they haven't been working for you.
