Fell through the ground....

Hi I was hunting hornets gallard etc in event area 2 at roughly pos [17185, 26007, 76] when the hillside I was on disappeared and I fell into water. On the map I was nearby the lake but not in it. Swam to the surface and all the surroundings were greyed out and I had to press T to escape.

weird

 

you met "waters below"
safeguard to not fall into endless nothing and T ing out is only way to get top side

 

It happens to me ever so often at Valiant Firebase. I regard it as a free bath.

 

This can happen anywhere, the more lag the higher probability.

If there is 'real' water nearby, you can swim out into it and then crawl ashore.
