[2023-02-13 13:46]   Announcements
Site Patched to 2.23.4:
I pushed this update out late last week but had not had time to post the announcement yet, better late than never. The update primarily focuses on Alpha Strike conversions and aligning those with the fixes and errata I had noted over the last year or so. Details of what's included are as follows:

  • Fixed an issue where the proper movement factor was not being calculated for LAMs during Alpha Strike conversions.
  • Fixed an issue where TSEMP heat was not being accounted for during Alpha Strike conversions
  • Fixed an issue during Alpha Strike conversions where computer rounding was causing some damage values to be off in rare cases.
  • Fixed an issue during Alpha Strike conversions where Long-range damage calculations were potentially off due to incorrect long-range heat adjustments.
  • Fixed an issue where certain weapons were not having the appropriate "insufficient ammo" check performed during Alpha Strike conversion.
  • Fixed an issue where units with Long Toms could not load the design into MegaMekLab depending on the type of ammo carried.
  • Fixed an issue with superheavies where the asterisk listed in the readout would improperly indicate the number of criticals the equipment took up.
  • Fixed an issue in the Administrator interface where the Manage Submissions hyperlink took you to the incorrect URL.
  • Modified Alpha Strike calculations to account for errata made to the JMPS and SUBS specials, and how those now impact Point Value calculations.
  • Modified how the REAR special was calculated based on errata to use heat from rear-firing weapons only.
Enhancements and Changes
  • Changed how the SRM special was displayed to remove the dash for long range damage. For example, instead of showing as SRM2/2/-, it will now show as SRM2/2. This was done to align with the official Alpha Strike cards.

NOTE: Any forces or units impacted by the above fixes and/or changes have had their stats recalculated to ensure accuracy.

Tamar Rising Now Available in Print and PDF!:
Silence falls across the Jade Falcon border, and slowly, reports reach Lyran space: the Clan’s warriors, so long a threat to the Steiner realm, are gone. Powerful ambitions rush to fill the vacuum that follows. Former Clan citizens both recently assimilated and long conquered grapple with a future no longer defined by the will of the Falcon warriors. An Arcturan general dissatisfied with Tharkad’s ineffective rule forges her own destiny. A Clan denied the glory of Terra redefines itself through battle and conquest. And a mercenary unleashes her reborn command to claim vengeance for past calamities.

Tamar Rising is a BattleTech sourcebook providing full details of the events in the former Clan Jade Falcon Occupation Zone from 3151 to mid-3152. Included are a full historical summary of events in that region of space, personality and unit profiles of key players—many appearing here for the first time, and game information to bring it all to your BattleTech tabletop.

Note: This zip file contains two PDFs. The first is the book itself. The second is the Campaign Map, which with the physical book is a 26” x 38”, double-sized, laminated poster.
