Now that I've been able to finish the mod to work on a multiplayer world, when a player breaks these blocks, it throws a fatal exception in the console/logs. I didn't have any compiling errors, so not sure why if fails in-game. Could this be an issue with importing it from 1.7.9 to 1.8.0 ? If so, is there a fix for it? I don't get this issue when I break my other mod (also from 1.7.9) blocks. The difference is those blocks are all "gravel" and these blocks are ores. Do let me know what else you may need to help resolve it. Thanks! -Steve

Issue comments
hopefully, these are the ones you need. Workspace 2 (mod in question) and workspace.settings file.
I removed the turn redstone on and turn redstone off procedures for each of the blocks and that stopped the exceptions. Not ideal of course, since I wanted these blocks to be redstone enabled. Is there an alternate way to do this in 1.8.0?
Block is placed - redstone is enabled
Block is destroyed (by anyone/anything) - redstone is disabled
You can do this by using these events, but then lock the code and remove the following lines in the block code:
EntityPlayer entity = Minecraft.getMinecraft().player;Of course, in such case, you can't use entity dependency, which is not required for the redstone event.
MP compatibility is being improved, but this is a long process as thing get quite complicated on MP.

Thanks Klemen, I re-added the two procedures (turn on and turn off), then edited the code to remove the row mentioned from both the When block destroyed by explosion and When block destroyed by player.
Placing the block is not enabling redstone. Is it that I need the EntityPlayer entity = Minecraft.getMinecraft().player; only for the player section and NOT for the explosion section of the code?
or is it that I need to remove all particle effects on my tools, ingots, ores and armors too? That's the change I needed to get the mod to compile for MP. I'll test this theory in the morning assuming I don't hear back before then.
