I do understand that, depending on one's hardware, TerraTech can be rather demanding. I understand that it is impractical to keep all the loose resources and parts laying around indefinitely. That would slow down FPS and use up more and more memory until, eventually, the game would likely crash. In particular, I understand the practicality of removing loose resources and parts that are beyond the edge of the player's map or beyond their line-of-sight. Personally, though, I disagree with the usefulness of having loose resources and parts disappear after a few hours of time. As long as they disappear after leaving the edge of the map or line-of-sight, isn't that enough? Players and techs are constantly moving around, so unwanted loose material should disappear sooner or later. The reason I bring this up now is because I recently lost a huge pile of raw Celestite Shards that I had been mining (via Auto Miners) near my manufacturing base. This Celestite mine was close enough to my manufacturing base that I could actually still see the growing pile of light blue shards in the distance. I had been using a fast tech with lots of Thimble Collectors to occasionally ferry them to my manufacturing base, both to build parts and turn them into Resource Blocks. All was well for a long time. By this time I had gathered over half of them and the mine, itself, became exhausted. Without further need for the Auto Miners, I sent them back to inventory. However, I got distracted with building a bunch of parts that I was missing in order to use a big blueprint from my previous game. Hours went by. I finally finished and decided to go back to get the rest of the Celestite Shards to clean it up and make sure that I did not forget them. Except... they were suddenly GONE! I estimate that I lost the equivalent of between 1 and 2 GeoCorp Resource Blocks, or roughly 120 to 240 units. (BTW: Each GeoCorp Resource Block costs roughly 30,000 BB from a Trading Station!) It's not just resources that suddenly disappear after time. I've routinely seen this happen to loose parts near my manufacturing base. And by "near" I mean within range of my tech's guns.
