Details:
1. Start a networked MP game with 3 clients 1, 2, 3. 3 is host, 1 and 3 are
allied.
2. While it is client 1's turn, plan actions with client 3: 2 recruits and
moving the leader to a village.
3. End client 1's turn so it's now client 2's turn. See attached screenshot
for what it looks like from client 3's perspective now. The fighter is the
first recruit, archer second.
4. Switch to client 3 and delete the planned leader move.
5. Delete the planned fighter recruit.
6. Plan to recruit a fighter on the same spot the previous fighter had been.
7. Repeat steps 5 and 6 until the game crashes. It always happened when trying
to delete, with a deterministic backtrace, but not always after the same
number of repeats I think. Most of the time, I had to do 2 deletes and 1
recruits following step 6.
