DS/RoG wormholes have showed up in Hamlet twice in the last week. I tried jumping in the first one. My cause of death was listed ,(in the Morgue), as "decorative hole?". I thought it may have appeared because I was experimenting with world size. That game I had tried "Medium" sized, which turned out to be tiny; all the biomes were squished together.
A later normal size Hamlet revealed another DS wormhole. I quashed my curiosity, but thought Klei should know about this fun, but deadly bug...
I'm loving Wormwood! Now the jungles aren't scary.
Thanks for the beautiful game.
