Well, here's some console information, at the bottom of my message. Using Firefox I opened up the campaign I am working. I then opened the API in a separate tab. I did not open any scripts in the API window. Clicked on Restart API Sandbox. Things seem to compile well. I only can judge success when the three Script LIbrary APIs I have: Spinning up new sandbox... "-=> TokenMod v0.8.61 <=- [Tue Aug 11 2020 20:54:05 GMT+0000 (Coordinated Universal Time)]" "-- True Page Copy v1.0 -- [Mon Apr 03 2017 18:32:50 GMT+0000 (Coordinated Universal Time)]" "-=> WeaponArcs v0.1.3 <=- [Tue Aug 04 2020 13:16:25 GMT+0000 (Coordinated Universal Time)]" I repeated 4 and step 5 occurred again very quickly. I decided to wait for a little while and watched TV/played around on Facebook for about 5 to ten minutes. I then c licked on Restart API Sandbox for the third time. A fair bit of time passed, at least ten minutes, before I got a similar message to 5, above. This was an unacceptable amount of time, of course. I then looked at the console. Nothing really seemed to have changed. I wish I had copied it beforehand to compare. Nevertheless, but between the two horizontal lines is what I copied. I hope this is of some help.
