You cheat. In cases like yours the detection quest didn't notice the item before you used it, so you'll have to manually edit the quest book. Type /hqm edit to get an operator quest book and shift-left click the quest for the sky blue wool to set it to complete.
I got the lag too. Lived for it until I finished with needing the smeltery (for quests and early game material recycling), then dismantled the smeltery.
This basically sums up what most people seem to be thinking lately. Once you hit Miner's Delight^4, it's all downhill. I wish Parcel would switch around some parts so that you get Atlarus and Adamantine later on (since it is the end game metal) and spread more of the metals out, basically balancing the game so it isn't so well done in Lost in Space and half-assed in Lost in Time.The place is a cake-walk compared to when the guys were zipping around like crazyNow they are all moving in a very slow and normal pace. Only place that is really horrible is the idea machine (Tip, turn down your volume before loading the area) and the nether-sphere^4 (All those blazes and ghasts)... Then again, Miners Delight ^4 is rather laggy,,, And Red is just annoying...
You have to use the projector and blueprints to successfully make the multiblock.
Trophy list, I didn't list the visible ones because those aren't that frustrating to find
Note, that before you end the game you do need to get the exchanger, which makes finding these a lot easier
ghast 3 blocks above reactor on the wall, hank ztones block
slime - directly underneath a red lamp in reacotr room (on the corner) Agon block
Mooshroom - high on the wall in reactor room in a fancy circuit block
chemroom
endermen - britt block 5 floor first level, close to the glass on the floor
magma slime - brit block 0 near the corner on first floor
pig - directly over the elevator (top floor)
VM
Squid - in one of the two spiral factory blocks on the floor
observ
golem - one of the four large steel pillars holding up the travel anchor platform
snowman - between observatory and spatial incubator (top center)
Those trophies are in plain sight. Bat is to the left of the reactor. Cave spider is behind the me interface in spacial IO. Zombie Pigman is behind the fusion reactor i think (May be fission reactor. i dont remember)
Ocelot is near the bottom of the obsidian sphere you spawn in. Its amongst the strange obsidian looking blocks with stars in them. (Some sort of a chiseled gold block)
Thanks, I knew there was something weird with those but never got round to looking around them properly. Now I just need to find the other 3 (I assume) dogs
first dog thing is in the upper region of the middle floor of the biosphere. Other one is in the rutunda, i believe on top of maybe the second ring from the bottom. (Its not inside it, its on the top)
