Try a thorough wash with some soapy water (and a thorough rinse). Its not too much water - if the crown were underwater, it would be dead. There are 4 things that make sundews unhappy:
1. Not enough or too much sun
2. Not enough water
3. Not enough humidity
4. Bugs!
The twisty stems and leaves and lack of tentacles says sucky-bugs to me. You have the water and humidity covered. Sun? But that wouldn't cause the deformities - that is strictly a bug thing. You may have to repeat the soapy wash a couple times.
