Token light and other token visibility.

The following images show a token light torch as it moves up one square to show token but when moved back down one square the token is still visible. Token moves an additional one square down then token becomes invisible. Depending on the token lights movement same issue happens to other tokens. One square to show the token, move back one and token is still visible. Move an additional one away and tokens become invisible.

No Extensions. GM view.

I'm confused by the picture a bit. Is there an LoS blocker in the gray area in the middle between the tokens?

I'd probably have to see that campaign map in action to be able to test and write up.

No LoS blocker. Open space. Does it in any campaign. The campaign shown you have. Same as yesterdays.

Here is a different campaign. I will put it in the dropbox folder,
