I've never seen a "puddle" in a crypt. There are flooded corridors that you have to swim through but crypts are all on the same level which is different from burial chambers. There should be a way out of your puddle unless you ran into a game bug.

It might have been one of the double decker corridors (one stacked on top of another), with water in the lower level, and a hole in floor on the upper level. I seen that a few times. I never fell into the hole, but assume it would have been pretty bad.

Another trick to conquer the swamp is bring a hoe. Use the terrain raising function to make nice flat water free paths through the swamp. I saw a guy doing that in a video, and felt like an idiot after watching it. I had built raised pathways made out of wood through the swamp. Chopped a lot of trees to do that. Heavy sigh.

If you find fire vents in the swamp, that spawn surtlings... do the opposite. lower the terrain around the fire vent, until water leaks in. Just dig a moat around the vent. Don't get too close to the vent (i'm not sure if you can destroy the vent with a hoe, didn't want to find out). When you get the water in a ring around the vent, the surtlings spawn in and die instantly on contact with the water. Free coal and cores forever.
