Factorio 0.15.9 Science pack Recipe Bug/problem?

[RonkestDonk]

Hello
ive been playing factorio for the last couple of days since i bought it
but ive been encountering a problem while automaticly crafting science packs
it seems that blue and purple science pack recipe requirements keep changing randomly

for example
purple science packs the Production science packs first required (Electic Engine Units, Pumpjacks, Electric Furnace's) to be crafted
and all of the sudden they need Assembling Machine's 1 instead of the pumpjacks

also the blue science packs Science pack 3 Required Assembling Machine's 1 first and now they Require Electic Mining Drills.

it really confuses me why this would randomly change progressing through the game.

hope someone can give me a explenation about what is going on because im clueless
