Hello!
Don't worry, it's no disturbance at all!
With you demo I could verify that there was indeed a bug in hiding. I hope to have fixed that with the version 1.3.7 I've just released.
Also, I may have jumped too quickly to a conclusion on my latest reply, so I feel it is important to correct myself as well. The spritesheet size you were using was actually correct, and there was no need to double it down like I recommended. The way I coded the 8 directions occupies a second character sheet, it does not extends the original one.
Lastly, a side note... your spritesheet for the idle pose is not vertically aligned with the walking and dashing frames, so it causes a weird displacement when the poses change. That is easily fixed making sure the frames are properly aligned between files! ;]
I hope with this fix we're out of the buggy woods, but do let me know if you find anything else not behaving properly!
