Troops automatically return onboard after successfull invasion

[Agonos]

Hello,

I've noticed that my troops systematically return onboard my ships after invading a colony. It's a bit disturbing and i wonder if it's a new feature or a bug ?[&:]

Ships automatically pick up troops. Garrison troops on a planet that you do not want picked up.

Troops teleport back onboard transports if you helped allies capture the planet and they have majority of forces planetside afterwards. Same goes for AI then they help you capture the planet - AI troops will be teleported back after victory. This is better than having all allied troops for free after victory :]
