I was watching the delivery with a grin on my face in the middle of the night when the incident occurred. Apparently, there was a serious bug in some environments that caused Tofu to jump unbelievably when moving, severely damaging the gameplay. Moreover, we had no idea how to reproduce the bug, which was very troubling. However, the developers found a suspicious code and probably succeeded in fixing it. No, I have not been able to confirm that it was exactly cured, but I believe it probably was.
