This just goes to show that we should not rush into options such as BU and segwit.
Just imagine what would happen if we rushed to implement bitcoin unlimited and this happened, the price would drop significantly. Hopefully we will see a permanent fix for this in the future because this is the third instance of this happening. The numbers should be back up soon but the coders need to fix whatever bug is causing this, It's the third or fourth time that I've seen this since February.
