Basically the title. Multiple users of the Meatballcraft modpack (I am the dev for it) have reported not being able to use shift + left click while dragging the mouse to mass dump items into the ae2 terminal.

The modpack uses the latest version of PAE2 (0.56.6 at the time this is being posted), Neeve AE2 (1.6.4), and other AE2 addons that (to my knowledge) do not change the way terminals work.

Nevermind, the issue is on AE2 side, I tested this with non-forked mousetweaks and the issue still persists, feel free to disregard and close this issue.

This was caused by a change in MouseTweaks interactions starting in AE2UEL v0.56.5. I'm addressing some issues with those interactions, one of them being the mentioned shift + left click mass transfer functionality in AE2-UEL/Applied-Energistics-2#455, so this issue should be fixed when that gets accepted.

wow you are amazing!

Fix merged by AE2-UEL/Applied-Energistics-2@1316f03 if you want to close the issue.
