Cryztallz Start at the pinned Broken and Updated Mods and CC in the Forum you're now in (for Mods and CC), which is for the February patch and on. If your issue isn't solved by that, you'll still have to 50-50. But 50-50 is the fast way to test mods, especially if you quickly rule out whole big categories, like all your build/buy CC, at once, leaving much less. How to Use Mods and CC has instructions on how to do the testing accurately (a lot of online guides unfortunately miss some important info.)
BUT... we're expecting UI changes in the March 17 update to accommodate the new Marketplace. That patch will definitely break several mods that alter that game UI. You will need to come back to check that thread too. When there's a new thread, you can log in and pick the bell symbol at the top right to "follow" the thread. This way you'll get notifications as news comes in about what broke and when it's been updated.
