The LCD.SumLogsTop value might not be getting calculated during the SumAll step of processing a cruise.
In SumAll.cs line 48 there is a list of 36 fields that need to be summed. But on line 73 when enumerating the fields the for loop stops at 35 elements, leaving out the last element "LOGSTOP".
SumLogsTop is only used in the TIM report, 3V records when reporting secondary product number of logs.
Update: It appears that this issue doesn't impact 100pct cruise method or Sure To Measure trees, because the TIM report has its own duplication of logic for summing up values for the 3v records. In this duplicated logic it correctly summing up topwood logs.
