Error Creating Custom SPAs

[honestaly]

Prerequisites and Pre-Issue Checklist

• I'm reporting the issue to the correct repository:

• MegaMek

• MegaMekLab

• MekHQ

• I've tested the issue against at least the latest MILESTONE version

• I've asked on the MegaMek Discord about the error

• I've reviewed the BattleTech rules and MegaMek documentation, and I've confirmed that something isn't working as intended.

• I've searched the Github tracker and haven't found the issue listed

Severity *

High (Major Disruption): A major feature is broken or incorrect, but a workaround exists.

Brief Description *

Following the directions to add a custom SPA I modified the configuration files and it causes MekHQ to crash on loading or creating a campaign.

Steps to Reproduce

1. Add this to customspa.xml in the universe folder
   `
   &L3;
   &BOOLEAN;

   `

2. add this to the end of defaultspa.xml in the same folder
   <ability> <lookupName>alpha_strike_antagonizer</lookupName> <displayName>Antagonizer (AlphaStrike)</displayName> <desc>Antagonize Opponents Pg 92 Alpha Strike Commanders Edition</desc> <xpCost>10</xpCost> <skillPrereq> <skill>Piloting/Mech::Regular</skill> </skillPrereq> </ability>

3. make sure both files have a blank line after the end xml tag.

4. launched MekHQ 50.0 and tried to create a new campaign or load a campaign and got this error.
