Topic: prevent ppl from harvesting the same plant
I've checked this with Helioptris plants only: It is possible for two ppl to harvest the same plant. This shouldn't be possible because it opens the chance to gank ppl with less developed extensions.
Say a highly developed player deploys a field container next to a bunch of plants. Then because these plants are the next to a terminal/outpost, someone who just got a Laird arrives and respectfully targets a plant which the other doesn't. Chances are that the high level harvester claims these plants for himself so he starts to always target the plants which the low level harvester does. This of course to drive him away. He will eventually succeed because the high level harvester has probably double the cycle time so the low level harvester will hardly be able to fill his cargo. The situation gets even worse as groups of Helioptris plants get rare.
The problem is similar to multitagging, but the solution is different. Of course, if harvesting the same plant was impossible, the one with the lowest locking time wins. But as plants aren't being tagged, the low level harvester has a chance to lock a plant the high level player doesn't expect.
The same would apply (haven't checked this) to ore/liquid fields although it isn't that much of a problem because these fields are mostly very large. Still it is possible piss off low level players.
If this gets serious, you will have people leaving with one thing in mind: "What a *** comunity".
