Universal Remote 0.9.2
Tinkers Construct 2.7.3.30
Actually Additions r119

Using the remote removes the Area of effect mining with the tools form these mods.

Kind of hard to describe, watch this video:

Also some tools seems to do doubleclick after you have used the Universal Remote.

Well shoot... the player proxy was leaking into the player interaction manager!
Fixed in 0.9.3

This is still happening in 0.9.3

Created a custom modpack with the Twitch launcher, with these mods:
Actually Additions 1.12.1-r19
JEI 1.12.1-4.7.8.95
Mantle 1.12-1.3.1.21
Tinkers Construct 1.12-2.7.3.30
Universal Remote 1.12-0.9.3

Basically the latest versions of all the mods.

Pastebin of console: https://pastebin.com/GGaMLH7a

Edit:
Same thing still happens with only Tinkers Construct or Actually Additions loaded, and not both.

How is that possible.. I tested carefully and it was definitely fixed.

CHECKS

OMG... I uploaded the wrong version of 0.9.3 which didn't actually have the fix in it.
This is why I shouldn't try to fix bugs when I'm in a hurry. :(

I'm so sorry. Thank you 10000% for finding this and re-reporting my bad upload!
Please try 0.9.4!
