A few thoughts and questions that came up while testing,
@NermaN !
First things first, you did us an incredible service.
1. Sometimes ModPlague is unable to edit my main.npdm (error) - I checked on the computer whether the file was read-only or not. The other possible source for error might be a folder name that is too long.
I was able to resolve it through one of these changes - I'm just not sure which one it was.
2. Does the backup assignment reset after every system restart? I thought it would stay due to mod plague saving the assignment in some file..
2.1 Is only one assignment (donor-game) at a time? As soon as I assign completely unrelated donor-game pairing, the first pairing seems voided - the donor of the first pair starts itselg not the assigned game.
3. Would it be possible to view in the donor selection which donors are currently assigned to which game? Best would be not only by ID but by donor name.
4. (Asking if you know why it lags implies that you would not remedy it if you would know, lol!)
5. I'm sure that it will come soon since this tool should be considered an essential for all the layeredfs-users in this community: Will someone create a GUI for this?
(Sorry in advance if any of these questions already came up in this thread).
