how do love potions work? do they work also for mating a V3 with a V4?
Love potions are great. When you use one of one of the tamas youare mating, when they connect as adults they automatically go up in status to "True Love" or 4 hearts with one another and if you do it about 24 hours after being an adult I think you can also mate on the second connection after that.
As for mating two different versions using a love potion, I tried it once but I don't think it worked out as well since they both have different points of time when they can officially have children. It's 24 hours after adulthood occurs for the V3 and I think you need a job first for the V4. I suggest doublechecking that I could be wrong.
