Crash upon breaking blocks

[Mustang351c]

Whenever breaking blocks, (creative mode for doing some testing if that matters) I get a crash. This happens with any block from this mod. Here is the report:
crash-2015-11-10_16.51.56-server.txt

Looks like this is the cause.
If this is not fixed of course.

AdvancedSystemsManager/src/main/java/advancedsystemsmanager/tileentities/manager/TileEntityManager.java

Line 248 in 1ddb3b0

if (inventory.getTileEntity().isInvalid())

AdvancedSystemsManager/src/main/java/advancedsystemsmanager/tileentities/manager/TileEntityManager.java

Line 614 in 1ddb3b0

activateTrigger(item, valid);

ive found out that this only happens when you break a block that causes a command to fail. so if you break the inventory the cable is reading it crashes also.

Looks like the developer has stopped development on this for a while. If he does not come back then I will fork the code and continue it because I really do love SFM and this is just such an improvement upon that :P
