What steps will reproduce the problem?

Ran LFR Imonar at roughly 8pm PST 2018-02-17 and was getting some of these messages (see attached screenshot)

When this happened 2/3 of the raid was dead (including myself) after taking a warlock teleport across 2nd bridge, tripping wires.

I did not see these messages on the 2nd pull. I have also not seen these on heroic or normal.

What version of BigWigs are you using? (Stating 'latest' is not useful)

88 5a0d494

Do you have an error log of what happened?

n/a

Any additional information?
