v.2.1.1:
Fixed an issue that caused illegal moves in games without increment. With increment, this release will behave almost identically to v2.1.0.
If Rengar is asked for a move with 33 milliseconds or less on the clock, it would previously skip the deepening loop and play some move interpreted from uninitialized garbage. In practice, I observed this to be the last move Rengar played. Now we search to depth at least 4 provided the search time stays under a millisecond.
This only matters for games played without increment. H/t to Lars for flagging the underperformance in such games.
