What is a star trek and how do I get planes in it?

Hi, I updated the app 2 days ago and got new tasks including having planes level 37 (for jewels). I’m also on player level 30 and bar full but won’t go to level 31, and no sign of Star Trek. I have 2 planes level 30 but can’t merge them.

I contacted the developers and this is the reply I got:

“The highest player level is 30, and the highest aircraft level is about to be updated to level 40.

We are about to open higher levels and add more aircraft

Star Trek has a little accident, and this week we decided to update the player level first.“

I hope that helps.
