The same here. But I hope the package is actually not in Houston anymore, but somewhere on the ocean.
Regarding the umlauts, it may have been just a problem with the delivery notification mail, which had a 7-bit-encoding (which means it couldn't contain any special characters). But even if the real address on the package misses the umlauts, I'm confident that the letter from the customs office will reach me anyway.
