Build: 1.8.14 3886 SERVER NAME: ELEON GAME STUDIOS - OFFICIAL US SERVER SEED-ID: NONE If applicable: MODIFIED PLAYFIELDS: NO Reproducibility: YES ALWAYS Severity: MAJOR Type: GLOBAL Summary: Xeno Blocks Fail and is Destroyed in Base Description: If placing Blocks on top of the xeno block, even with only 1 space unsupported, the xeno then fails to support. I have tested this with other typed of blocks and most fail. The setting for xeno blocks in a BA could be set incorrectly as it fails to support anything on top of it unless everything underneath is completely filled in with blocks, which does not make sense. Steps to Reproduce: 1) Place 3 high xeno full blocks on ground (or any height), 2 pillars with 1 block at the top in between for a total of 3 blocks at the top wide (as an example) 2) Now place 3 or more steel blocks on top of the middle xeno block. After the 3rd steel block, the xeno block, even though it is almost fully green, fails and crumbles completely. 3) This can be reproduced and is repeatable on the the Official US Server.
