#1862 Nasal runtime error in adv. weather

[Nikolai V. Chr.]

I am using advanced weather and Terrasync:

1: I loaded up at KXTA
2: I set "marginal VFR" metar on.
3: I switched location to KNUQ while the weather dialog was open.

Using 2016.2.0 build today on windows 7 I got this:

Nasal runtime error: setprop() value is not string or number

Oops, I noticed the was stuff before that:

AW does not support teleportation - that has never worked and never will because it creates weather around you - since the launcher now allows you to start with AW already running, if you teleport after such a startup you will crash AW and need to restart.

(I believe if the reset would trigger a Nasal re-init, the problem would not occur).

[James Turner]

Reset does a Nasal re-init, but 'relocate' (reposition) doesn't. Maybe we could disable AW before doing a repostion, and re-enable it afterwards?

[Frederic Türpe]

Has this been done yet ?

[James Turner]

Also, I'm confused how this could show up as 'setprop' being undefined, that seems like something more fundamental going wrong.

Can confirm on current next. The actual error is now:

Nasal runtime error: vector index -1 out of bounds (size: 1)
