So how do I get more loot chests through cheat mode? I activated it and I can only find the one in front of the stables and the one in the mayor's mansion. Where are the rest of them?
Once the red chests are looted they stay empty. They're intended to jumpstart things: cash to buy stuff right away, useful things, ingredients for potions, a few actual potions, etc.
Besides the ones
TSSG59 mentioned there's one in the Witch's House (not accessible until after you retrieve the Chalice). The one in the Mayor's mansion is replaced by a new one once you become Mayor. There might be others but I haven't bothered to look for them.
- Some chests can disappear at certain story points, be sure to loot them before that happens. The first chest in the mansion does this. So does the one at the Witch's House when you remodel it for Liandra.
