Open 2.1.0: Chunk claims reset without warning

[GreaseMonk]

Version:
2.1.0

What is the bug:
ATTN: this is for version 2.1.2, could not find a better place to post this bug for the developers, if in wrong forum, please forward or let the developers know in any way, i'm just trying to help!

With the new chunk claiming system:
Right mouse button will clear all chunks without warning.

left-click the chunk map icon in the inventory, and pressing middle mouse button very quickly after, ALL chunks will get removed without warning.

I use middle mouse button to speak to my friends, so i use it pretty often, that is how this bug confronted me.

Mod & Version:
FTB Infinity 2.1.2

Paste.feed-the-beast.com log:


Can it be repeated:
yes, sometimes for mmb, and always for right mouse button

It seems like i am having the same issue.
Still running 2.1.1 over here but when i click rightmouse or "unclaiming" a chunk, unclaims all chunks.

The GUI hows that only the selected chunk is unclaimed but the counter is saying 0/1000
When you close the GUI and re-open it. all chunks are gone.

It seems this only happens to your own chunks and not someone elses.
Tested it both as OP and de-OP, there is no diffrence.
