Lo-Fi Games

The "is secret" setting of the TOWN item may be carried over to the new town after the override.
In a MOD that overrides a bandit's hideout to a neutral town, my character is attacked by the neutral forces when he passes through the town's gate.This is almost certain to happen if there is no save load between before and after the override.
Once it occurs, a save load does not cure it.

I think it's more likely said mod has not changed the "is public" flag to true on the override. Should probably report it to the author.
