I know in game he’s not present in the ruins…but with sans being sans…You gotta add him in there somewhere. Maybe when your about to leave the ruins you can knock on the exit door and sans is on the other side telling a knock knock joke? ---

This isn’t really an update. Rather a help post. @richard I am still getting the “e is undefined” error. But i have already fixed the pxt.json file like you showed. But it seems like there’s something else giving me this error. I saw you showed that the fancy text extension had a bug that did that. I update it but the bug is still there. I don’t know what’s wrong with it anymore. It might be one of the extensions. But I can’t say anything for sure. [https://makecode.com/\_U5zbk62PrbJi](https://makecode.com/_U5zbk62PrbJi) ---

hi I’m new something similar happened to me in a baldi’s basics remake I was making. I had all the sprites and one day they just disappeared. all of them. there were a lot though, so if you also had tons of sprites that might be the reason. that is a really cool game though ---

Actually @richard I was wrong. It still doesn’t work. I just failed to show the error properly.

ah, understood! so there are two things happening here. the first is a bug with my font editor; it was putting the wrong annotation on the fonts it generates. i just pushed an update to the font editor to fix that and i’ve also fixed both of your custom fonts in this project: [https://makecode.com/\_a3hT1ugE2Vek](https://makecode.com/_a3hT1ugE2Vek) the second is a bug in makecode that i only [recently discovered](https://forum.makecode.com/t/cannot-read-properties-of-undefined-reading-length/33981/2). basically, this has to do with calls to `pauseUntil` that pass in a function that just checks a variable. you can work around it for now by wrapping that variable in two `not` blocks (two `not` blocks cancel each other out so this doesn’t actually change the behavior). i also fixed this in the above linked project in other words, do this: ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/3X/c/e/ce2b96c41985f5b7e6d0f4bd10afa197cb5befbf.png) instead of this: ![image](https://us1.discourse-cdn.com/flex020/uploads/makecode/original/3X/8/6/86baa9beb19c29e461ed21e1d970ff867f781ee1.png) [Previous page](https://forum.makecode.com/t/undertale-arcade-devlog/32377.md?page=5) [Next page](https://forum.makecode.com/t/undertale-arcade-devlog/32377.md?page=7)
