### 1. xsEffectAmount effect cMulAttribute and cAddAttribute with attribute cAttack/cArmor¶

Description: When using xsEffectAmount and cMulAttribute or cAddAttribute to modify cAttack/cArmor, the effect does not change the attack/armour at all

Expected Behaviour: Expected behaviour is demonstrated using the following example:

Reproduction Steps:

1. Create a new scenario or RMS
2. Create a new XS script with the following code:
  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 void main() { const int cGenghisKhan = 731; const int cPierce = 3; // Both of these work correctly as expected xsEffectAmount(cSetAttribute, cGenghisKhan, cAttack, cPierce*65536 + 5); xsEffectAmount(cSetAttribute, cGenghisKhan, cArmor, cPierce*65536 + 5); // These however do not do anything. xsEffectAmount(cAddAttribute, cGenghisKhan, cAttack, cPierce*65536 + 5); xsEffectAmount(cMulAttribute, cGenghisKhan, cArmor, cPierce*65536 + 5); // To make cAddAttribute and cMulAttribute work, we need to currently use the old format: // xsEffectAmount(cAddAttribute, cGenghisKhan, cAttack, cPierce*256 + 5); // xsEffectAmount(cMulAttribute, cGenghisKhan, cArmor, cPierce*256 + 5); } 
3. Include the script in the scenario or RMS
4. When a game is played using the scenario or RMS, The attack and armour of the Genghis Khan unit is unchanged
