- fixed a bug with Flagstones of Trokair. There was no easy fix (cloned objects deleting stuff from their parents...) and I ended up using a "garbage collect at end of turn" technique the way I did with the ActionStack. As a result, the memory print of a turn will become bigger, and even more bugs might occur at the end of a turn... I'm ready to discuss this, although I think it's the best solution (in terms of result/amount of work) given the way abilities work right now
- Test suite now gives the number of failed/success at the end of the tests
