Build: All versions tested, up to 1.5.3 Mode: Creative Mode: SERVER NAME: N/A SEED-ID: N/A If applicable: MODIFIED PLAYFIELDS: None Reproducibility: Always Severity: Moderate to low Type: Out of bounds bug Summary: The bounds checking for expanding a selection during creative mode, when it goes out of bounds, causes unrpedictable results as the code has gone off into la-la land. Description: Creating a selection larger, or just outside of the bounds, of a structure/ship in Creative mode causes unpredictable results and the client to be out of sync with the server. Steps to Reproduce: 1) Spawn a blueprint, any blueprint will work (In my example I used the Rebar 3 stock blueprint) 2) Make a selection using the selection tool 3) Expand the selection to outside of the boundaries of the ship 4) Use cut or remove or delete on the ship (At this point, the client will be out of sync with the server) 5) Paste, or do another operation on the structure data - Notice that the operation has failed or has invalid results. (Another option being something like adding/removing a block, pasting the data somewhere else, etc.) 6) (Optional) Reconnect/reload to the server/game to see that the servers version of what the ship/structure looks like wasn't what the client previously thought it was.
