How hard is it to sit?

Well, after getting 19 positions setup to sit and stand in different parts of the trolley, I was able to start working on handling multiple avatars. The only problem is that once an avatar sits on a prim, the sit target seems to change to default. It doesn't matter where you change it to, any new avatar joining the link chain sits on the object as if it didn't have a sit target defined. I tried adding a child prim to the object in case it needed a child prim to assign the next person to sit down on. At the moment, I am pulling my hair out. I really don't want to put redundant code into every single prim that this trolly has. At times like these, LSL scripting language encourages server lag. From Dedric Mauriac via blogHUD.com
