Good day, for some reason the tournament isn't working =(
Any ideas why? Maybe too many rounds?

UPD
Reducing the number of rounds started the first battle, but no further fights occurred =(

Upd2
I might have found the cause: the bot dismissed/lost the starting hero and leveled up another one. Since the tournament is designed specifically for battles with the starting hero, the entire script likely broke. I've now checked the box that losing the starting hero = defeat; I'll test it.

I think this could be a combination of an issue in the template and a limitation of the game engine.
The StartHero mode was selected for the tournament, meaning only the starting hero should participate in battles. However, the condition for defeat upon losing the starting hero was disabled. If the bot dismissed or lost this hero, the engine could no longer select a participant for the next tournament battle, which caused the tournament to stop. The assumption from UPD2 is most likely correct.

Additionally, 10 points for victory were set in the template—that's 19 rounds lasting up to day 198. Official templates feature a maximum of 3 points and 5 rounds.
Judging by the test results, the current engine handles longer tournaments unstably.

The editor allowed such an unsafe combination to be created.
I have released a new version 1.2.7 in which:
- defeat upon losing the starting hero is automatically enabled for any tournament;
- the tournament is limited to three points, meaning a maximum of five rounds.

For templates already generated with the old editor, I recommend checking the box for defeat upon losing the starting hero and setting no more than 3 points for victory.

After this, the tournament should function significantly more reliably.
Thank you for the detailed report and testing.
