TL;DR: We don't have the trackable (and feel sorry for you if it means it is still missing), but stumbled upon its discovery code.
The story: I discovered this trackable/coin when I cracked the cache "Msportis Coinlihaus der 2." and then was able to reverse-engineer some Coins/TBs of the owner Msporti as well. By pure chance / luck while testing out possibilities for this I also came across this TB/coin. We hope that it's okay that we discover it, if not, feel free to delete this log. TFTC/TFTT 😉
