Played Escape from Innsmouth again, this time using Steam, version 1.02. The game still soft locks after Turn 14.
Three investigators: Preston, Wendy, and William
Main Riot was at Pier.
Small Riot was enabled.
Deep One Hybrid was enabled.
Deep One was enabled.
Fire was enabled after Torch.
Agent Craven was in Library.
Most map tiles were revealed besides eastern portion.
Soft lock occurs right after Main Riot moved to Pier.
The game did not go into combat checks, as it should have, with the current monsters and soft locked instead.
Only working commands were Set Fire, End Game, Investigator Eliminated, and Message Log.
EDIT: The bug is definitely related to the Main Riot monster, with the constant horror checks and such, when it isn't visible on the map.
