RFTools (Legacy)

2.42:

• The shield camo system is now a LOT more stable. In the previous versions of RFTools you could actually corrupt the world by putting in a wrong thing (item, energy cell, ...). This should no longer be possible. If it can't render it then the shield will simply be invisible.
• If you got a corrupt world due to a wrong block in the shield this then there is a way to fix this with this version of RFTools. To get your world back simply set disableShieldBlocksToUncorruptWorld to true in the config. Load your world, remove the offending block from the shield projector. Exit. Then set the flag to false again and you can continue playing and use a better block in your shield.
• Shield blocks and the matter transmitter beam blocks should now relay be indestructable. With the shield system it is now possible to make a wither killer as it can cope with the explosion of that mob. However, note that you still have to protect the projector (move it far away from where the wither spawns).
• The tooltip of a screen now shows the number of modules.
• The shield collision detection system now considers lit tnt, xp orbs and other non-living entities the same as items.
• Fixed a problem with the crafting of larger/transparent screens crashing if the original screen wasn't placed in the right (top-left) slot.
