Only, that is not true. ZecMurphy did acknowledge it on one of the dozen threads in this forum on this topic. In fact, you created this thread long after that acknowledgement. The attitude of this thread whether intentional or not, rapidly became a demand that N3V drop everything to fix the issue and provide constant updates. Now this sort of behavior is common on "social media" as discussions tend to devolve into tribalism where peer pressure is exerted on posters to "take a side".
Perhaps, it is worth taking time to consider the N3V viewpoint. They have been very quiet in this forum for roughly 6 months and so their quietness on this issue is not a symbol of avoidance but of an overall shift in the way the company responds to the forum in general. It helps to understand that the gaming industry is suffering at the moment due to poor sales. Many gaming companies expanded during the period of draconian lockdowns when users had more free time to play games. Unfortunately. this boom in business did not continue after the world began to get back to normal. And now announcements of layoffs and cancellation of projects are all too common. It may be that N3V is working full speed on getting a new product out the door to boost revenue. Certainly, work on TRS25 has begun and the sooner it is released the better it will be for the bottom line of the company.
So given that the Trainz Gallery is a non-revenue producing service of the website and if the problem is beyond the skills of the web team to fix. Bringing in outside help to fix the problem might not be a choice that N3V wants to make right now. Or as others have suggested, it is simply a low priority in the bigger process. After all, the system does still work with manual uploads as can be seen by the presence of screenshots all over the forum.
A few years ago, Tony disclosed they had run a survey of first time buyers of T:ANE and he cited some of the results. First, only 10% had downloaded anything from the DLS and only 20% had logged into this forum. The former is certainly the reason that much time and money has been spent in expanding the in game download system for both DLS items and Trainz Store purchases. It really has come a long way since the early efforts of TS12. The latter shows it is a fallacy to cite the opinions of the forum as representing the "will of the people" which N3V should respond to with the highest priority. There are official ways to get responses such as the helpdesk and bug reports that are much more efficient than using the forum as a virtual speaker's corner of Hyde Park to voice your grievances. I'm sure that everyone here wants the brightest future for N3V and wants to do nothing to harm that future. So maybe it is time to let this thread and all the others like it just die.
