seared glass and lava tanks not holding lava in transit

[telocity]

When building smeltery I like to build a few extra seared tanks and/or seared glass to take with me to lava pit and fill up.   Much quicker then transporting a dozen buckets.   But in the bid dig mod when I put them back down after filling them, they are empty.    Just wondered if anyone else had this issue, it is very minor I know.

 

Thx!

Never mind, I'm an idiot.  Assumed the "Big Dig"  was 1.6, but it is 1.5 so that's why tanks don't hold lava in transit.  Please delete this topic admin. 

 

Thx.
