Hi! 

Longtime "casual" user of bitsy, I've just come back to the editor after about a year, and I'm having some bugs that I've never encountered before. They're hard to describe but basically the avatar, sprites, items, and tiles, seem to freak out a bit while editing. The changes in the following images are all from just playing the game and then stopping it.  The outer ring here should be my tile, not the items and/or sprites.

I can save the game, re-open the editor and it works fine for a while, but the issue quickly creeps back in.

I'm on a Mac OSC 14.3.1, and have had these errors in both Safari and Firefox.

I'm actually teaching a class where we're using bitsy and my students are having the same problem on Macs (OS unknown off the top of my head) in Safari. 

Any solutions I can offer my class? Thanks!

Hello, I am having this same issue. I am using Bitsy for the first time today,  so I can't offer a permanent solution. The temporary solution I have found is toggling "animation" on and off on my avatar,  it makes everything return to normal until it happens again when returning to editing after playing. I am also using firefox! Hopefully a better solution is found!

Thanks gothswine. I should say I have a temporary solution too: clicking the arrows to switch to another room in the "room" editor (whether or not one exists), but, as with your solution, this is temporary, and problems seem to get worse when they recur.

Just adding that one of my students is working on a Windows machine and had the same issues.

Thank you for raising this issue. I have been using Bitsy for more than 3 years now, and encountered the same bugs as you described for the last year or so (I am using Windows by the way). My guess is that it is somehow related to one of the latest updates, so maybe an earlier version of Bitsy would be more stable. I, however, have not yet tried this method.

Agreed—thanks for raising it. I'm having the same issues. Also, I'll confirm it's appearing on Mac Safari/Chrome. And Windows Chrome. It's kind of challenging to work with.

I encountered this constantly, on Windows and Firefox. I had to make it work for a game jam last weekend. My solution (workaround) was to regularly refresh the page (F5). I'm not sure if saving before refreshing was important to do, but I saved lots anyway.
Also, maybe a separate issue, but my exits and endings kept going down to 1/1 (there should be several more). Refreshing also resolved this (temporarily).
