[0.9.6] Crash when placing blueprints with underground belt

[ssilk]

When placing blueprints with (fast) underground belts, they won't be connected. In some situations the game crashes then, I found not the rule, when it crashes, but these two saves should provide enough reliable examples:

(I think this bug is not very important and could wait a bit before fixing.)

Edit: if this bug is related to the other bug (removing inserter logistic removing the bug fix mod), I think it isn't needed to fix it within 0.9, because new players barely can make it happen.

The bug was caused by the beacon and it is fixed for 0.9.7
