FTB Infinity ~ Strange Basalt Biom underground?

[Lennart45]

Hey guys, I tried to google it, but couldn't find anything.
I just found some blocks that absolutely didn't make sense together.
I was in an abandoned mine, like one of those shafts, and eventually I found two or three charge pad batboxes and a few blocks of quartz and behind that there were a lot of redstone blocks and more batboxes and then I found water pads from the mod Agricraft, and suddenly basalt and a strange burning liquid, I couldn't pick up with a bucket. Beneath the basalt blocks, I found three empty chests, more batboxes, redstone blocks and also 4 blocks of emerald and even some loose beds, like honestly it didn't make sense at all. Does anyone know where this come from or what it is for?

That's what I found:
-1 double chest full of charge pad bat boxes
-64 basalt
-2 stacks redstone blocks
-6 emerald blocks
-10 beds
-3 chests
-30 blocks of quartz
-1 1/2 stacks of reinforced stones

*update* I found some reinforced stones a bit isolated from the other things I found..
*update* Behind, beneath and next to them were nothing. Anyone got an idea? :S

Thanks for answers!

I'm not 100% on this, but what version of infinity are you playing?

There was a bug at one time where block IDs were a bit wonky and you would find strange things like this.

Apart from that, I have no idea.

There's written "FTB Infinity evolved 1.7 (v2.6.0) Minecraft Version 1.7.10"

But I think strange blocks were more common then, if it'd be a bug? And I haven't found any unusual stuff beside that.

If i remember correctly, it was a strange interaction with Biomes'O'Plenty... but again.. my memory is foggy
