Portals not portal-ing

Actually- what they are not doing is producing trains... they used to... I cant think of anything thats changed.. now, only one creates trains- the others- nothing... same train setups- pointed right way, with conductors, navigational directions... what gives?

I thought MAYBE the makeup was unable to be finished- like I was using rolling stock that i did not re-download- but i dont think thats it.

malaru - can you please be more specific about exactly which portals are not behaving correctly at the moment?
Names - and KUIDs - so that we can check them out too.
Have you configured the ones you're using again recently?
Check Content Manager for Out of Date assets, particularly portals and enabling scripts.
