Issue description:
Setting up a space chamber and builder combination set to collect all items in the space chamber area will cause a dupe when the builder is being tick accelerated.
Steps to reproduce:

1. Set up a space chamber and link it to a builder configured to collect items. Power the builder and put a chest or other inventory above it and set it to work nonstop.
2. Place a tick accelerating block (I used torcherino) near the builder and activate it.
3. Throw an item into the space chamber's active field and check the inventory on top of the builder for said collected items.
