I been doing the mono ichi tools, normally I tried it on lightday, but the last time I went on 4 consecutives breaks was on a fireday. I know the moon phase vary alot, but none the less the difference of my level and of the recipe is huge, and I been doing the tools for quite a while, and seen this breaks not only on the tools but other low lv synthesis lv 30 below, been breaking, since two updates ago, I have reported this before through the support page. I do agree the I know ill break some, 2, 3 tops on some stacks, but going 4 breaks consecutive.... kinda makes you wonder
