Not sure these are bugs, but they are irritating.
Crop dust and Compost (purchased) You have to use 2 of each on the plot. Be more convenient to use just one like the scarecrow and seeds. If it is supposed to be a gold sink, raise the price. But please lower the usage to 1.
Crop dust. I use it, but it does not seem to make a difference on how many times I need to prune the crop. 1 - 2 times pruning with crop dust. 1 - 2 times pruning with out crop dust.
Not sure if Compost and Scarecrow is additive on the final crop. I usually end up with a + 4 when using both and a + 4 with just the scarecrow.
