Campaign crashes after finishing scenario

[Romulus13]

I've finished Hasty alliance scenario in the campaign with Konrad.
After killing the leader I get the Map generator error: Lua cave generator (it is also present in the attachments section).
The save game of the last turn is in the attachment (only the leader needs to be killed).
This is my copied build of the game:
The Battle for Wesnoth version 1.14.0 (f5fd48d-Clean)
Running on Microsoft Windows 10 (10.0.16299)

I downloaded the save and killed the leader but the issue did not reproduce for me.

It seems to it happened if I overwrote the replay save. When I skipped it it, everything went onwards per usual.
P.S. The game is awesome guys. I love it !!!!

well since this is an error in the random map generator it is not unlikely that it only happens if the random map generator randomly generates bad data, which would naturally be unreliable to reproduce.
