Due to various API changes introduced in factorio 2.0 a few things were broken for the mod:

1. You can now select the same entity multiple times in a block due to how 'choose-elem-button-with-quality' works.
2. It is impossible to get the capacity of the quality accumulators through the API, so it simply works by formula "base_cap * (quality.level + 1)", which is correct for DLC, but I can't guarantee it will work for other mods.
