Moving thru damaging warppoints?

[Suicide Junkie]

Very strange.

In one v1.67 game I'm playing with my brother, there was a funky warppoint going out of my homesystem.

I put off the exploration for obvious reasons, but once I ran out of nearby planets, I sent a colony ship through. It survived, found some nice worlds, and I sent a bunch more.
I figured that the warppoint mush have been one of my shield-disrupting WPs, instead of the damaging ones.

The first time I noticed something was wrong, was when my long range explorer ship (out of fuel) was about to finish it's 4 year journey home.
It went through the warppoint, and BOOM! It died.
Since then, the warppoint has eaten all of the ships I've sent through. The only path around this warppoint is long enough that colony ships run out of fuel, so I had a heck of a time sending reinforcements to those worlds.
