Thankyou
Yes that makes sense cos i'd put a few oddball rides in using arbitrary changes since the last save that worked. I checked them all and they seemed to be working, with stats present... then i deleted them one by one and it still didnt fix it. I had to use a previous save to get on track again, and have since rebuilt all the same rides too without issue lol - but it had to be one of them.
Thankyou again for your help!
