I've been keenly following the new developments at github and did a retry at LFPG, after seeing that https://github.com/felix-b/atc/issues/245 (planes not cleared for take-off) had been corrected.
I confirmed that the correction worked perfectly there, but now it is happening at LPPT: planes piling up at runway 3, not being cleared for take-off. As you can see in the picture, the first departing plane (Ryanair 101) is already lined up. Also, arriving planes keep coming even though a plane is stopped on the runway. I tried it a couple of times, with the same results.
I'm using build105. Things were working at LPPT back in Alpha 1, so something got broken in between.
All subsequent arrivals are requested to go around
Notes:
since AI pilots don't implement the go-around maneuver yet, they land anyway, then excurse the runway and continue moving on the ground forever (TODO: link to this issue)
