This error occurred at 11:11 PM EST. I attempted to add an anycomponent block into a list block to create clones. I began receiving this error. This was not consistent and I was unable to reliably produce this but it was intermittent.

Thanks for reporting this.

I’ve been making some changes to how the blocks execute. Eventually the changes will speed up how fast the blocks run, however, this looks like a bug I’ve caused in the process. I’ll get a fix out as soon as I can (best case later today, worst case early next week). Sorry for the inconvenience.

It should be fixed now. Let me know if you run into that issue again.
