WinSPMBT v 3.0 Bug?

[Suhiir]

In the patch notes I see :

12) Artillery effectiveness against armour was too high and the following changes have been made to the code
* Only units in the shell explosion hex will receive top hits (except cluster munitions)
* Penetration in the blast circle outside the shell explosion hex has been reduced for shell splinters (except cluster munitions)
* Armoured units may now suffer a suppression-only hit (hit by shell splinters message)
* HE penetration on armour now needs more overpenetration to be certain of a penetration effect. If equal, 25% will go through, if overpenetration of 6, 90%
* More chance of immobilisations (track hits) rather than kills especially if the shell size is small

Yet when playing the game (I origionally had the free version then later bought the CD and installed it over the top) I'm getting some "interesting" effects.

#1 - HE artillery does NOT supress armor in the same or adjacent hex, nor do I see any shell splinter message.
#2 - HE small arms fire DOES supress everything in the hex and adjacent ones, I see lots of shell splinter messages.
#3 - I've had a few incidents where aircraft rockets/missiles have killed multiple vehicles in a hex and adjacent ones.
#4 - AP/ATGM/Sabot/HEAT rounds supress other vehicles in the target hex but NOT the target vehicle.

Am I crazy or is my install bugged somehow?
