First: don’t expect to see log output when you didn’t configure logging for a package.
Second: I really hate when a bug vanishes and I don’t know what finally fixed it. How can I now be sure that I will not change that part again accidentally? Now don’t tell me that would not have happened if I had tested each change more thoroughly. Just don’t. I think it was the timestamp issue which I believed worked but didn’t no most probably it was the heartbeat seconds timestamp thing I forgot to multiply with 1000 at one point or whatever else. I really don’t know. But it was probably the heartbeat thing. Anyway I now have colorful pictures, now they must be made to look good. Which is not the fun you might think.
*edit* by now I am calling this the “Factor-1000” or “Kilo” bug 😉
