problem with W2Control32

Hi, i am Rafael Souza from Brazil. I am modeling a reservoir with 10wb and 10 br. The prototype working of following way: wb_1(River,2-17)- wb_2(reservoir,20-71)(principal branch) wb_3(River,74-77)- wb_4(reservoir,80-93) wb_5(River, 96-114)- wb_6(reservoir,117-126) wb_7(River,129-141)- wb_8(reservoir,144-160) wb_9(River,163-167)- wb_10(reservoir,170-181) In the w2_con file: BRANCH G US DS UHS DHS UQB DQB NLMIN SLOPE BR1 2 17 0 20 0 0 1 0.00020 BR2 20 71 17 0 0 0 1 0.00000 BR3 74 77 0 80 0 0 1 0.00020 BR4 80 93 77 36 0 0 1 0.00000 BR5 96 114 0 117 0 0 1 0.00020 BR6 117 126 114 48 0 0 1 0.00000 BR7 129 141 0 144 0 0 1 0.00020 BR8 144 160 141 65 0 0 1 0.00000 BR9 163 167 0 170 0 0 1 0.00020 BR10 170 181 167 67 0 0 1 0.00000 In the program W2control32 the system shows as a asterisk,all branchs cross through of principal branch at the same segment. Would I like to know if this is just a bug of model or my system is working like that?
