New version seems to bug at specific points

Hello everyone,

this is less a code problem and more an overall CC one.
The last couple days, i am getting responses about my program "Ultimate Wood Chopper".
I didnt changed anything the last whole month and now the turtle doesnt work correctly.
Players are experience turtles, which arent placing pipes or even dirt blocks correctly or at all. One guy said, that they got spit out instead of getting placed.
I dont know what to do now, because the code looks completely fine to me. I looked into the changelog of CC and nothing special was found by me, which might would have cause these problems.

DID something changed? Or do i have to change something in my program?

They might just have set it up wrong :P/>

5 people setting it up wrong in the past 3 days? And all the weeks before everybody was a genius and did it correctly? I dont think so…
You cant do a lot wrong: Place stuff into the turtle/chest and press the freaking right button and the turtle does all the job. Easy! And doesnt work anymore…

Well, you might want to figure out what part is disfunctioning. It might be a bug.
And nobody is going to sit and read all those 2000 lines of code to solve your problem :P/> It is long xD

It selects a slot and should place the block or pipe..
But it doesnt. Players had this bug every once in a while, but the last days everybody seem to have them…
Reinstalling CC seem to work most of the times, but it wont be a solution if the problem occures everytime again.
Line 1485 is the part where the most stuff doesnt work.
