I have a strange bug in Ignition 8.1.17 (also in older 8.1.6)
In one of our project, we have 1 Gateway Timer Script and 1 Gateway Scheduled Script
Afer opening the project, if we open the Gateway Events, go to timer change the delay on the script, go to the Scheduled tab, the title of the script is still there, but the script itself is empty.
If we open the Gateway Events, go to Scheduled tab first, then go to Timer and change the delay, everything is fine.
Only thing that is specific is that the Timer script title contains a space in the middle.
