It always switches to the last open tab.

It doesn't depend from choice of tab.

command: tabteleport_ctrl_tab
command: move {"by": "lines", "forward": true}
command: insert {"characters": "\n"}
plugin rewritten command: switch_to_tab

Some output from logs.

Could you tell your Ubuntu version, please?

16.10

My version is 14.04, maybe something changed for 16.10. I will install 16.10 on a virtual machine and fix the problem, but only on upcoming weekends.

Don't worry. I've figured out what is the problem.
This package https://packagecontrol.io/packages/TabsExtra has been installed. So seems there is some conflict.
