fixed. but the api is not counting anything on rockets... could not find why

Oh ok wasn't really using it anyway, just testing the different options.

I have another issue, maybe it's just because you updated your library.

I setup an array of hologram sign to show me the count of certain item in my logistic system.

When I launched the game again this morning the number wouldn't update anymore and then I realized it's because the "input to print" setting all reseted. The "count item on logistic" setting wasn't selected anymore and they all just showed the last item count before I closed the game. Had to go an select "count item on logistic" on everything again. The item I selected in there was still right, so only had to select the input to show.
