Assistant changes tactic whether u use instant result or simulate match.I am surprised how knap approved instant result testing
The reported issue is he might just change the player role like WM-A to WM-S or something like that not the tactic settings but I haven't notice such behaviour. This is fix patch for 17.2 that might be related
- Fixed issue with assistant manager not following user's instructions when user holidays match and ticks use formation + use current team when possible
Anyway, we will never have a perfect test setup unless SI give us their internal testing tools. We can only minimize the randomness within our control.
