Is there an altitude limit for airships or balloons?
I was flying with the Dragon Ship and I saw some floating islands, so out of curiosity I got closer, and when I got very close, I tried to go higher to get onto the islands, but at a certain point it wouldn't let me go any higher, as if it had reached a limit. I tried adding several more balloons (the ones specifically for the Dragon Ship), but it didn't make much difference. Can anyone tell me if this limit really exists for floating ships or balloons? And how can I reach those floating islands in the air?
