It's funny. I replaced the lamp with another one. Elevator worked. I restored the lamp back -- elevator did not work. I changed X-coordinates of the lamp. Now elevator works again. What a hell is going on? =))
Yep, me either. 5 or 7% of hooks used, can't get myself onto roof garden.
Reported this bug via game support yesterday, now hope they will fix it asap. I had plans =)
