Mod version
1.0.3 - 1.21

Minecraft client crashes when you drag-right-click a tank slot with a non-empty Chemical Tank from Mekanism.
(I know tanks are not supposed to hold gases, but a crash is a crash)

To Reproduce

1. Open tank interface
2. Drag-right-click a tank slot with a non-empty Chemical Tank from Mekanism
3. Enjoy the crash window

Expected behavior
At least not crashing.

Logs
[Crash log]

Fixed in 1.0.4

(just an addition to the report)
*It seems to crash even with other fluid tanks that for some reason can't accept a fluid (e.g. in case when the selected slot is occupied), not just gases.

it has nothing to do with mekanism or fluids, but with mouse drag clicking

I assume the crash report is identical
