Update causing nothing to happen when signal thrown

Since the Rust update, the plugin isn't worked for me. The players get the signal like usual, but when they throw it nothing happens. No message in chat, no heli, nothing at all. RCON error below..

It didn't work on the previous plugin version and I updated it to the latest and that didn't fix it. Thanks!

Changed Status from Pending to Work in Progress

I dont know if this is related, but were getting intermittent signals thrown doing nothing.  They just go on the ground and  stay on the ground forever, and then do not save correctly

The save issue is fixed, but you still have null entries in your list.  It’s not related to the issue above and is separate.

NullSaveList.cs
 

Load this and then use the command in the console to clear any null items in your save list. Open the file to see what the command is as I can’t remember off the top of my head.

With regards to the other error which prevents helis being called, can I ask if any of you use other plugins which also act on Supply Signals?

The only other plugin we have that use signals is Bradley Drops.
