LoW Story Replay Bug

[LemonySnid]

I recently replayed Human Alliance. At the end of "The Treaty", the screen went black and I couldn't do anything. Furthermore, no new save for The Chief Must Die was created. I was able to fix this by my previous replay of The Treaty.

I tested a few other story events (in LoW) and the bug occurs there as well.

So it seems that if a story scenario from legend of wesmere is replayed and a replay file already exists, the game will break at the end of the replay.

The Battle for Wesnoth version 1.14.9
Running on Apple macOS 10.14.6 (18G103)
