After the latest mods updates (mainly playing with the whole Bob suite and RSO/Angel's infinite ores), when I loaded my map all the infinite non-vanilla ores from Bob were deleted, while the non-infinite ores stayed where they were.
Seems to be the case on a brand new world too but I didn't wander very far for obvious freshly-born player squishyness, though I confirmed spawning of normal Bob ores (and no infinite ones whatsoever).
That's about it.
And no, the may 31st patch didn't fix it. Unless Bob wanted infinite ores to be removed
