"One pill makes you larger, and one pill makes you small. And the ones that mother gives you don't do anything at all. Go ask Alice, when she's ten feet tall." Um, yeah, so... this happened. "And if you go chasing rabbits, and you know you're going to fall Tell 'em a hookah-smoking caterpillar has given you the call. He called Alice, when she was just small." It's no trick of perspective. "Goodbye, Cruel World...." What proceeded this was a number of rapid-fire "Connection to server lost" messages, too short to really even notice, but they've happened enough times I know how to notice them, followed by an attempt to land on a planet that resulted in my passing through the ground, reappearing in the upper atmosphere a couple times, then sitting still to wait for the planet to load, which it did. I then landed, and thought something seemed "off". Took a look at me and, well, you can see what happened there. All of this, on the current build, in MP, on the Official Vanilla server.
Woo! I see a "Fixed in Next Update" tag has been added. And thanks for the likes Razzle and Kass - buy I don't think you're supposed to "Like" bugs ;-) I will say though, there is a certain fun-factor to being mouse-sized. Perhaps a means of acquiring this "status" could be investigated. Perhaps as a side-effect of eating Alien Spiked Mushrooms? Just give it a duration so it wears off after a time, or "cure" it by consuming some other odd alien consumable?
