Greetings.
Not sure if this qualifies as a bug but here goes.
Tactic: Coach strictly follows formation
Team/Formation:
Starting lineup
PG, PF and C substitutes
PG, PF and C reserves (just in case)
Note: As feared, the PF substitute got injured and the PF reserve came in, so "lucky fan" crisis averted there.
The goal was to give the starting SG and SF the 48 min for training purposes.
With 7 minutes left the (in name only) HC subs in the reserve C for my starting SF clearly going against the selected tactic/formation and ruining the training goal
