Oh man... The basic Katyushas are pretty ineffective, i've made 13 BM-13 Katyushas to defend my borders and to upgrade to BM-13-16 later, now is 93th turn and because of Mannerheim Line beta 4 is not going to be save game compatible, right? Im kinda upset =\
in RedDefinesUnits.lua find
Code:
[RU_T34_76] = RU_T34_85,
and add below
Code:
[RU_BM13] = RU_BM13_16,
[RU_IL2] = RU_IL2M3,
[RU_IL2M3] = RU_IL10,
saves should be compatible, but not all changes are applied then, better start a fresh game before reporting anything with a new beta.
and remember, this is called "beta" for a reason.
