Hello,
Not sure if this is a legitimate bug, but wanted to add it in case.
Reproduction:
1. Have L1 clearance
2. Plan a move with the timeline feature to hire any specialist (when available)
3. Attempt to plan another move (launch sub etc.)
4. Game pushes to prompt to buy L2 clearance with only one move planned in the future.
It is possible to plan sub launches x4 with no issue, but planning hires of specialists seems to halt this ability.
Possibly a B-class bug as it stops some more advanced planned moves from happening - ie, hiring an infiltrator and immediately launching an attack with him.
I'd just like to take this opportunity to thank the devs, it's a lovely game, and I've been evangelising about it to everyone I know. All the best with future development, and I'll be paying for my L2 clearance as soon as I can afford to. All the best!
