If you are experiencing issues with the mod, this will most likely sort you out. However, if this does not fix your problem, contact me directly here.
1. Make sure you are running a legit non-pirated version of The Sims 4 with the latest gamepatch installed.
2. Make sure you have Script Mods and CC enabled in your The Sims 4 game settings.
3. If you have installed a previous version of the mod, make sure you have deleted all the files from it before installing the new version.
4. Make sure you put both the file titled basementaldrugs.ts4script and the .package file directly in your Mods folder (no subfolders).
5. If this does not solve your problem, it might be a faulty or outdated Mod or piece of CC that is causing a conflict. In that case, try to move all your Mods and CC (except Basemental Drugs) out of your Mods folder and into a temporary folder, boot up the game, start a new game (as to not interfere with your already saved games) and see if the problem still persists.
6. If step 6 solved your problem, you need to start the tedious task of dragging Mods and CC back into your Mods folder and start up that new game again. Try putting in 5-10 pieces of CC and Mods at a time and remember what you put back in. It is tedious, but it is a surefire way to easily pinpoint which Mod is causing the conflict.
