Ah sorry about double reporting, I wasn't sure it was the same problem and I was obviously uberly ANXIOUS I could miss those 2 pieces of art. Indeed I got them as well at level 13.
I ran into a small annoyance just in my previous game : it happened when the (only) drill had just levelled up enough so I could set up a 3rd waypoint. I can't report very accurately because it was in the middle of a passionate play session, but basically it happened so I was always aving only 2 waypoints (#1 and #3). The drill would be going to #1, then ignore #3 and behave like it was out of waypoint. When clicking, I could set point #1 again but not #2. It took me a few seconds to figure out there was a new 3rd waypoint, and I got out of the loop using the reset waypoints button. Maybe it was due to an extremely bad timing of some sort on my part (like setting up the 3rd waypoint the millisecond it was going through the second one or something).
On a side note : I wasted a day after meeting my objective, merely looking at the island and other messages. It is so charming and filled with details, and we barely get the chance to see it during the normal course of the game ;)
To go offtopic a bit and talk about Kablooey, I really liked how you had to figure the game system and logic itself (Maybe I didn't pay enough attention to the tutorial ;). I found the game was quite demanding and figuring a tricky puzzle felt really rewarding. I didn't see it through its end, yet : I think twice before launching it, as you can't skip hours ahead of their ending time (or maybe you can but I have no idea how to) and once I got to the 5th hour it was a bit annoying to just wait most of the time for the later hours to show up, merely to test new ideas.
I still think about how to fix the radio building sometimes at night... (But please don't tell me what I might have missed, need to figure it out ;)
EDIT : To just expand on the bug I mentionned in this post, I have run exactly into the same trouble when the drill leveled to level 10 and got its 4th waypoint. Also, for some reason, the drill just ignored the border and got off the left side (I didn't test the right side) of the screen. I am running v1.037.
Here are screenshots of the occuring, in chronological order.
http://tinypic.com/r/5l848m/6 - First contact, where did my drill go?
http://tinypic.com/r/o9qngh/6 - Waypoint 3 is missing from the sequence after the drill upgrade to level 10.
http://tinypic.com/r/ogweme/6 - Going down in sequence, #2 and #4 become #1 and #3
http://tinypic.com/r/t69gf4/6 - After going through #1, #3 becomes #2 and with no #1 to go to, the drill attempts to escape.
