I may be up for helping test a chemistry mod. I delved into Sims2 chemistry quite a bit as I developed my Secondary Aspiration mod (https://modthesims.info/download.php?t=643015). Currently I'm using Cyjon's Debugger to query the chemistry between Sims. What is your chemistry mod going to do?
