No
GT++ Version as of state of this commit: ffb1b25
Version of the ScannerMod: https://github.com/GTNewHorizons/DetravScannerMod

Lemme have a gander what the ScannerMod looks for.. My ores are not GT OreTiles, they are just blocks. This is probably the issue?

yepp i think so.
BTW: Greg made them as TE's so they dont show up on XRAY-Texture Packs.

Yeah but that doesn't work at all.
As someone who has used all forms of 1.7.10 X-ray, I can verify.

Just Greg over complicating things for the sake of it.

So, what did you wanna do here?
Add an extra if?

Well ive tried to fix this with an extra if, but as it seems it iterates over the Gregtech Material List here:
https://github.com/GTNewHorizons/DetravScannerMod/blob/master/src/main/java/com/detrav/net/DetravProPickPacket00.java#L137.

i've added some more code that might fix this, but I cant test right now. will msg you in dc later

Fixed by GTNewHorizons/DetravScannerMod#6.
