I appear to have run into an edge-case scenario related to executing the "charinfo" command while the target is in the process of leaving the sector.

Specifically, I had Thorn Apple targeted and was trying to check what his licenses and faction standing were at. I pressed "k" (which was bound to charinfo) apparently right when he jumped. I recieved the error message below and all of his stats were zeroed out in the character info page. I wish I had thought to take a screenshot.

Below is the relevant information from my errors.log

Yes, I had plugins installed when this occurred. None of the installed plugins modify the UI in anyway or hook any functions, related to the UI or otherwise.

I believe it could be duplicated, but the timing is such that it's likely to be difficult, which explains why it hasn't been caught before.

EDIT:
Here's another log entry with a screenshot. (still with plugins installed.)

EDIT2:

I have verified that the problem does indeed persist when there are no plugins installed, and it's quite easy to duplicate actually. Just spam your charinfo button when a target is about to leave the sector (either docking or jumping).

Yeah, it's a known bug. You devs need to fix it! :)

Same thing happens when you target a group member that is out of radar range and look at the charinfo.

This started happening after the radar limit was introduced.
(This, the nil returing from a few functions, and the sector list appearing completely blank in ion storms even when there are targets in range...)

This lua error should be fixed in the 1.8.244 update.
